Useless deprecation message for driver import

[Brant Knudson]

When a driver is specified using the full name (as in, the old config file is used), for example if I have:

 driver = keystone.contrib.federation.backends.sql.Federation

I get a deprecation warning:

31304 WARNING oslo_log.versionutils [-] Deprecated: direct import of driver is deprecated as of Liberty in favor of entrypoints and may be removed in N.

The deprecation warning is pretty useless. It should at least include the string that was used so that I can figure out what to change.

    More useful message when using direct driver import

    In the Liberty release, we switched to using entrypoints for
    specifying the driver or auth plugin. The deprecation message
    didn't mention the driver name that was specified, nor did it
    mention where to look for the expected names, so it was not
    user friendly.
