Tomasz Trębski 94c5223f02 Integrate client with osc-lib
osc-lib library is foundation on which a CLI client
for openstack can be built. It is meant to facilitate several
aspects, that were previously hard-coded in client:

* keystone communication handling
* supporting multiple authentication methods (not only password)
* common authentication parameters (i.e. environmental OS_*)
* communicating over http with service endpoint
* interactive CLI mode

Thanks to those items, it was possible not only to drop
nearly 3k lines of code and replace them with osc-lib but also
increase reliabity of the client in terms of new openstack releases.
Also it allowed to greatly simpify existing set of unit-tests.
They are now testing only actual logic instead of mocking
entire process of calling shell (i.e. MonascaShell.run(args)) or
mocking HTTP communication. Both items are handled by osc-lib thus
not they are not subject of monascaclient unit tests layers.

Note:
This change is partial integration with osc-lib and its main
purpose is to move the responsibility of:

* keystone communication
* rest-ful communication with service endpoint

to underlying library thus allowing client to implement only
necessary functionality and not supporting boilerplate code,
mentioned above.
