Alessio Ababilov fba0cd51d9 Add apiclient.exceptions hierarchy ...

The new apiclient.exceptions hierarchy is more comprehensive
and it covers almost all HTTP error status codes. These
exceptions can be used in novaclient, keystoneclient,
glanceclient, and other client projects thus providing a
single inteface.

Users can have benefit from OpenStack clients raising exceptions
of known classes while now every client has its own classes making
difficult to catch, e.g., NotFound for every client.
