[cli] Add command to display db connection str

Browse Source 
There are several places in which rally looking for config file. Also,
there is a feature to transpit a config path while executing rally from
cli directly. This means that one installation of rally can load
different configuration files and use different database backends.

An ability to show exact database connection string which is used is
very useful for several cases:

1) before executing `rally-manage db recreate` to ensure that the
   correct database will be recreated.
2) before executing `rally-manage db upgrade` to ensure that the correct
   database is migrating
3) for debugging purpose to ensure that the proper configudation is
   loaded and the proper database is used.
