Bug Description

oslo.cache no longer exposes an unset method - only unset_many exists now. As a result, the implementation of sharding is broken.

The fix needs to be committed to: marconi.queues.storage.sharding

    fix(shards): guard against registering bad shard URIs

    Whenever an admin would attempt to register a new shard, the shard was
    admitted whether or not the shard URI actually existed, and whether or
    not marconi could handle shards of that type.

    This patch makes it so that a DataDriver instance is temporarily
    instantiated prior to storing the shard entry. This instance uses
    is_alive() to determine whether or not the shard can be reached/is
    supported. This applies to both PUT/PATCH. HTTP 400 is returned if the
    registration fails, as a result.

    To enable this change, the ability to create a dynamic configuration
    object was extracted from sharding.Catalog. Tests were written for
    this new function.

    The unit tests were updated accordingly, expanding the coverage of
    test_shards to include the new failure cases.

    Some changes needed to be made to handle new oslo.cache interface:
    - cache.unset doesn't exist - now using cache.unset_many
    - cache.get_cache() takes a URI, not a ConfigOpts
