keystone-manage doctor is pointing to wrong config section when warning about caching

[Michal Dulko]

That's what produced by `keystone-manage doctor` when no caching is enabled.

WARNING: `keystone.conf [caching] enabled` is not enabled.

    Caching greatly improves the performance of keystone, and it is highly
    recommended that you enable it.

There's no [caching] section - it's named [cache].

    Update doctor warning about caching

    `keystone-manage doctor` produces a message when caching is not enabled:

      WARNING: `keystone.conf [caching] enabled` is not enabled.

    In fact the config section is called [cache]. This commit fixes the
    message to point to correct [cache] enabled option.
