The means by which we extract and parse the version of an API object is
not specific to etcd3. In order to allow for a generic suite of tests
against any storage.Interface imlpementation, we need this logic to live
outside of the etcd3 package, or import cycles will exist.

Previous work by liggitt in 01760927b82 improved the boilerplate
required to run an embedded etcd server for tests as well as set up the
`*etcd3.store{}` for testing. A number of tests were not ported to use the
new helpers, though, either due to custom setup or due to inconsistent
use of setup options. A follow-up by stevekuznetsov in 6aa37eb0624
removed much of the inconsistency, meaning that most callers to
`newStore()` were simply using the default boilerplate and options that
`testSetup()` used.
This patch moves all users to testSetup(), adding options as necessary
to enable some fringe setup use-cases. With a unified setup, new tests
will not copy boilerplate they do not need and it will be immediately
obvious when reading a test if the client or storage setup is *not*
default, improving readability.

In a number of tests, the underlying storage backend interaction will
return the revision (logical clock underpinning the MVCC implementation)
at the call-time of the RPC. Previously, the tests validated that this
returned revision was exactly equal to some previously seen revision.
This assertion is only true in systems where no other events are
advancing the logical clock. For instance, when using a single etcd
cluster as a shared fixture for these tests, the assertion is not valid
any longer. By checking that the returned revision is no older than the
previously seen revision, the validation logic is correct in all cases.

Previously, this test assumed that:
- a global watch would return only an event for the key in question
- only the delete event in question would be returned
Neither of these assumptions are correct for an etcd backend as long
as any other clients are interacting with the system. This commit
makes the watch more specific and extracts the correct event.

When the original commit created the lease manager, this comment was
added to set the default test reuse time to 1s. Even at that time, the
comment claimed it was setting 10s. Instead of using this value, though,
new tests that did not call `testSetup()` started to use the default
configuration for production. This commit clarifies the intent of this
comment, moves it next to the code block that it actually applies to,
and makes use of this test-specific logic everywhere.

Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.

server if it is in a test environment. This allows us to catch coder
