Change-Id: I357387113652d15f643d925c6fe070b0d5298262

This change adds database support to the python-openstackclient
through a plugin and tests.

The support can be demonstrated through the implementation of
the trove command flavor-list which is now:
    openstack database flavor list

Use the -v or --debug flag to see the calls being made to the correct
flavor list function.

ubuntu@ubuntu:~$ openstack database flavor list -v
START with options: [u'database', u'flavor', u'list', u'-v']
command: database flavor list -> troveclient.osc.v1.flavors.ListFlavors
Using auth plugin: password

"Python 3.3 support is being dropped since OpenStack Liberty."
written in following URL.
https://wiki.openstack.org/wiki/Python3

And already the infra team and the oslo team are dropping py33
support from their projects.

Since we rely on oslo for a lot of our work, and depend on infra
for our CI, we should drop py33 support too.

As of Mitaka, the infra team won't have the resources available to
reasonably test py26, also the oslo team is dropping py26 support
from their libraries. since we rely on oslo for a lot of our work,
and depend on infra for our CI, we should drop py26 support too.

There's a typo in setup.cfg, it should be "universal".

Mainly, remove the pin in setup.py and remove the hook entry in
setup.cfg. Update from requirements while we're at it.

The new client adheres to the standards of the other clients
now. It prints out tables, uses ENVVAR's for auth, no longer
stores pickled json in a login token, uses openstack common,
and moves the cli operations into a v1 module for the future
of trove when it has a v2 api.

Please note for compatibility, the troveclient.compat module
has the old cli. In order to deploy it, amend the setup.cfg
to include the compat module.
