* cmd: update prometheus.NewProcessCollector args.
There's a new struct `prometheus.ProcessCollectorOpts` that is expected
to be used as the sole argument to `prometheus.NewProcessCollector`. We
don't need to specify `os.Getpid` as the `PidFn` of the struct because
the default is to assume `os.Getpid`. Similarly we don't need to set the
namespace to `""` explicitly, it is the default.
* SA: reimplement db metrics as custom collector.
The modern Prometheus golang API supports translating between legacy
metric sources on the fly with a custom collector. We can use this
approach to collect the metrics from `gorp.DbMap`'s via the `sql.DB`
type's `Stats` function and the returned `sql.DbStats` struct.
This is a cleaner solution overall (we can lose the DB metrics updating
go routine) and it avoids the need to use the now-removed `Set` method
of the `prometheus.Counter` type.
* test: Update CountHistogramSamples.
The `With` function of `prometheus.HistogramVec` types we tend to use as
the argument to `test.CountHistogramSamples` changed to return
a `prometheus.Observer`. Since we only use this function in test
contexts, and only with things that cast back to
a `prometheus.Histogram` we take that approach to fix the problem
without updating call-sites.
Because the package versions in go.mod match what we use in Godeps.json,
there are no substantive code diffs. However, there are some tiny
differences resulting from how go mod vendors things differently than
godep:
go mod does not preserve executable permissions on shell scripts
Some packages have import lines like:
package ocsp // import "golang.org/x/crypto/ocsp"
godep used to remove the comment from these lines, but go mod vendor does not.
This introduces several indirect dependencies that we didn't have
before. This is because godep used to operate at a package level, but
go mod operates at a module (~= repository) level. So if we used a
given repository, but didn't use all of its packages, we wouldn't
previously care about the transitive dependencies of the packages we
weren't using. However, in the go mod world, once we care about the
repository, we care about all of that repository's transitive
dependencies. AFAICT this doesn't affect vendoring.

Now that Pebble has a `pebble-challtestsrv` we can remove the `challtestrv`
package and associated command from Boulder. I switched CI to use
`pebble-challtestsrv`. Notably this means that we have to add our expected mock
data using the HTTP management interface. The Boulder-tools images are
regenerated to include the `pebble-challtestsrv` command.
Using this approach also allows separating the TLS-ALPN-01 and HTTPS HTTP-01
challenges by binding each challenge type in the `pebble-challtestsrv` to
different interfaces both using the same VA
HTTPS port. Mock DNS directs the VA to the correct interface.
The load-generator command that was previously using the `challtestsrv` package
from Boulder is updated to use a vendored copy of the new
`github.org/letsencrypt/challtestsrv` package.
Vendored dependencies change in two ways:
1) Gomock is updated to the latest release (matching what the Bouldertools image
provides)
2) A couple of new subpackages in `golang.org/x/net/` are added by way of
transitive dependency through the challtestsrv package.
Unit tests are confirmed to pass for `gomock`:
```
~/go/src/github.com/golang/mock/gomock$ git log --pretty=format:'%h' -n 1
51421b9
~/go/src/github.com/golang/mock/gomock$ go test ./...
ok github.com/golang/mock/gomock 0.002s
? github.com/golang/mock/gomock/internal/mock_matcher [no test files]
```
For `/x/net` all tests pass except two `/x/net/icmp` `TestDiag.go` test cases
that we have agreed are OK to ignore.
