In #3708, we added formatters for the the convenience methods in the
`probs` package.
However, in #4783, @alexzorin pointed out that we were incorrectly
passing an error message through fmt.Sprintf as the format parameter
rather than as a value parameter.
I proposed a fix in #4784, but during code review we concluded that the
underlying problem was the pattern of using format-style functions that
don't have some variant of printf in the name. That makes this wrong:
`probs.DNS(err.Error())`, and this right: `probs.DNS("%s", err)`. Since
that's an easy mistake to make and a hard one to spot during code review,
we're going to stop using this particular pattern and call `fmt.Sprintf`
directly.
This PR reverts #3708 and adds some `fmt.Sprintf` where needed.
This also adds the badCSR error type specified by RFC 8555. It is a natural fit for the errors in VerifyCSR that aren't covered by badPublicKey. The web package function for converting a berror to
a problem is updated for the new badCSR error type.
The callers (RA and CA) are updated to return the berrors from VerifyCSR as is instead of unconditionally wrapping them as a berrors.MalformedError instance. Unit/integration tests are updated accordingly.

This PR changes the VA to return `dns` problem type for errors when performing
HTTP-01 challenges for domains that have no IP addresses, or errors looking up
the IP addresses.
The `va.getAddrs` function is internal to the VA and can return
`berrors.BoulderError`s with a DNS type when there is an error, allowing the
calling code to convert this to a problem when required
using an updated `detailedError` function. This avoids some clunky conversion
the HTTP-01 code was doing that misrepresented DNS level errors as connection
problems with a DNS detail message.
In order to add an integration test for challenge validation that results in
`getAddrs` DNS level errors the Boulder tools image had to be bumped to a tag
that includes the latest `pebble-challtestsrv` that
supports mocking SERVFAILs. It isn't possible to mock this case with internal IP
addresses because our VA test configuration does not filter internal addresses
to support the testing context.
Additionally this branch removes the `UnknownHostProblem` from the `probs`
package:
1. It isn't used anywhere after 532c210
2. It's not a real RFC 8555 problem type. We should/do use the
DNS type for this.

Previously we were returning a Malformed problem type where RFC 8555
mandates the use of badRevocationReason and encourages including the
allowed reasons in the problem detail.
We've been using the newer "ready" order status for longer than the lifetime of any previously "pending" orders. I believe this means we can drop the legacy allowance for finalizing pending orders and enforce finalization only occur for "ready" orders without any feature flags. This is implemented in [c85d4b0](c85d4b097b).
There is a new error type added in the draft spec (`orderNotReady`) that should be returned to clients that finalize an order in state other than "ready". This is implemented in [6008202](6008202357).
Resolves#4073
Many of the probs.XYZ calls are of the form probs.XYZ(fmt.Sprintf(...)).
Convert these functions to take a format string and optional arguments,
following the same pattern used in the errors package. Convert the
various call sites to remove the now redundant fmt.Sprintf calls.
This commit adds a new WFE2 feature flag "EnforceV2ContentType". When
enabled, the WFE2's validPostRequest function will enforce that the
request carries a Content-Type header equal to
application/jose+json. This is required by ACME draft-10 per section
6.2 "Request Authentication".
This is behind a feature flag because it is likely to break
some number of existing ACMEv2 clients that may not be sending the
correct Content-Type.
We are defaulting to not setting the new feature flag in test/config-next
because it currently break's Certbot's acme module's revocation support
and we rely on this in our V2 integration tests.
Resolves#3529
Previously, CAA problems were lumped in under "ConnectionProblem" or
"Unauthorized". This should make things clearer and easier to differentiate.
Fixes#3043
To support having problem types that use either the classic
"urn:acme:error" namespace or the new "urn:ietf:params:acme:error"
namespace as appropriate we need to prefix the problem type at runtime
right before returning it through the WFE to the user as JSON. This
commit updates the WFE/WFE2 to do this for both problems sent through
sendError as well as problems embedded in challenges. For the latter
we do not modify problems with a type that is already prefixed to
support backwards compatibility.
Resolves#2938
Note: We should cut a follow-up issue to devise a way to share some
common code between the WFE and WFE2. For example, the
prepChallengeForDisplay should probably be hoisted to a common
"web" package
This PR reworks the original WFE2 JWS post validation code (primarily
from `verifyPOST()` in WFE1) to use the new "ACME v2" style of JWS verification.
For most endpoints this means switching to a style where the JWS does
*not* contain an embedded JWK and instead contains a Key ID that is used
to lookup the JWK to verify the JWS from the database. For some special
endpoints (e.g. new-reg) there is a self-authenticated JWS style that
uses the old method of embedding a JWK instead of using a Key ID
(because no account to reference by ID exists yet).
The JWS validation now lives in `wfe2/verify.go` to keep the main WFEv2
code cleaner. Compared to `verifyPOST` there has been substantial work
done to create smaller easier to test functions instead of one big
validation function. The existing WFE unit tests that were copied to the
WFE2 are largely left as they were (e.g. cruddy) and updated as
minimally as possible to support the new request validation. All tests
for new code were written in a cleaner subtest style. Cleaning up the
existing tests will be follow-up work (See https://github.com/letsencrypt/boulder/issues/2928).
Since the POST validation for the key-change and revocation endpoints
requires special care they were left out of the WFE2 implementation for now
and will return a "not implemented" error if called.
_Note to reviewers_: this is a large diff to `wfe2/wfe.go` and `wfe2/verify.go`
that Github will hide by default. You will need to click to view the diffs.

This PR removes two berrors that aren't used anywhere in the codebase:
TooManyRequests , a holdover from AMQP, and is no longer used.
UnsupportedIdentifier, used just for rejecting IDNs, which we no longer do.
In addition, the SignatureValidation error was only used by the WFE so it is moved there and unexported.
Note for reviewers: To remove berrors.UnsupportedIdentifierError I replaced the errIDNNotSupported error in policy/pa.go with a berrors.MalformedError with the same name. This allows removing UnsupportedIdentifierError ahead of #2712 which removes the IDNASupport feature flag. This seemed OK to me, but I can restore UnsupportedIdentifierError and clean it up after 2712 if that's preferred.
Resolves#2709
Boulder uses MalformedRequestError as a universal error. This pull request adds the RejectedIdentifierError and use it on a blacklist error.
For a client implementation, it is easier and cleaner to use an exception than parse the error message.

Several of the `ProblemType`s had convenience functions to instantiate `ProblemDetails`s using their type and a detail message. Where these existed I did a quick scan of the codebase to convert places where callers were explicitly constructing the `ProblemDetails` to use the convenience function.
For the `ProblemType`s that did not have such a function, I created one and then converted callers to use it.
Solves #1837.
This uses ProblemDetails throughout the wfe. This is the last step in
allowing the backend services to pass ProblemDetails from RPCs through
to the user.
Updates #1153.
Fixes#1161.
