Includes unit tests

Refs #9

This change affects both the kamaki.cli and kamaki.clients hierarchies
It is of semantic significance only
Backwards compatibility is preserved in kamaki.clients, so that
old code using base_url instead of endpoint_url will still work.

Names are changed for uniformity. Backwards compatibility is kept,
(old names are not dismissed)

Renames:
CycladesRestClient --> CycladesComputeRestClient
CycladesClient --> CycladesComputeClient

Users can still import and user CycladesRestClient and CycladesClient

Conflicts:

	kamaki/cli/commands/cyclades.py

Refs: #4583, #4563

Network connection has changed:
server create <usuall stuff here>
    --network-id=NETWORK_ID --network-with-ip=NETWORK_ID,IP
port create/delete are also used to connect/disconnect networks to servers

deprecated:
- all network-related commands at cli/commands/cyclades.py
- ip attach/detach
