Clean up shell display of slave info

Suppress links and improve display of slave information for the 'show' and
'create' commands. Also refactor shell.py to avoid repeating the code for
displaying an instance.

The revised print_instance method also avoids bug 1322822 where the order
in which attributes are queried can affect the display output.

Add visibility filter to datastore versions

Allows datastore versions to be hidden from all users except those
explicitly allowed by their tenant. Implemented via a visibility
attribute for datastore versions (defaulting to 'public'), and a
datastore version member table for controlling access to non-public
datastore versions by tenant.

This commit provides the client functionality for integration tests
related to the datastore-visibility feature.

Add a drop config-grp command in update instance

As per the current code in the client, there is no option to detach
the configuration group of the instance. This change gives a user the
option to explicitly drop the config group of the instance as part of
the instance update call.

Use 'replica' instead of 'slave'

Replace the mysql-specific term 'slave' with the more general term
'replica'.

In order to merge properly the client currently handles both 'slave' and
'replica' in certain cases. The 'slave' support will be removed completely
once the trove runtime is updated to be in sync.
