Update the trove docs to follow the docs theme

We were using the old theme on trove docs.

We should update to new theme, it includes the new logo as well!

You can see the difference in the themes here,

new, https://docs.openstack.org/admin-guide/
old, https://docs.openstack.org/developer/python-troveclient/
