Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.
The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).
However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.
This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

* Update redis.go
If the dgst key does not exist in the cache when calling HGET, `redis.String` will return an `ErrNil` which we need to translate into `distribution.ErrBlobUnknown` so that the error being returned can be properly handled. This will ensure that `SetDescriptor` is properly called from `cachedBlobStatter::Stat` for `repositoryScopedRedisBlobDescriptorService` which will update the redis cache and be considered as a Miss rather than an Error.

* Update suite.go
Add unit test to ensure missing blobs for scoped repo properly return ErrBlobUnknown when HGET returns redis.ErrNil.

Back in the before time, the best practices surrounding usage of Context
weren't quite worked out. We defined our own type to make usage easier.
As this packaged was used elsewhere, it make it more and more
challenging to integrate with the forked `Context` type. Now that it is
available in the standard library, we can just use that one directly.
To make usage more consistent, we now use `dcontext` when referring to
the distribution context package.

The "testing" package adds some flags in its init function, so utilities
that import distribution code may print a page of extra testing flags in
their help output.
This commit solves the issue by moving an import of "testing" in the
registry/storage/cache package to a new
registry/storage/cache/cachecheck package, which is only imported by
tests.
