* 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.

* redis metrics
it is working but metrics are not very useful since default buckets
start from 5ms and almost all of them are in that range.

* fix redis caching issue
earlier redis cache was updated when there was any error including any
temporary connectivity issue. This would trigger set calls which would
further increase load and possibly connectivity errors from redis
leaving the system with continuous errors and high latency. Now the
cache is updated only when it is genuine cache miss. Other errors do not
trigger a cache update.
* add back tracker Hit() and Miss() calls

Unit test coverge was increased to cover the usages of crypto. This helps to ensure that everything is working fine with fips mode enabled.
Also updated sha1 to sha256 in registry/storage/driver/testsuites/testsuites.go because sha1 is not supported in fips mode.

When uploading segments to Swift, the registry generates a random file,
by taking the hash of the container path and 32-bytes of random data.
The registry attempts to shard across multiple directory paths, by
taking the first three hex characters as leader.
The implementation in registry, unfortunately, takes the hash of
nothing, and appends it to the path and random data. This results in all
segments being created in one directory.

Radosgw does not support S3 `GET Bucket` API v2 API but v1.
This API has backward compatibility, so most of this API is working
correctly but we can not get `KeyCount` in v1 API and which is only
for v2 API.

It's possible to run into a race condition in which the enumerator lists
lots of repositories and then starts the long process of enumerating through
them. In that time if someone deletes a repo, the enumerator may error out.
