cyclades: Rename Port state from BUILDING to BUILD

Neutron API defines the 'BUILD' status. This commit renames BUILDING
 state of NIC to BUILD.

cyclades: PEP8 fix

cyclades: Refactor code for allocating IPs

Refactor code that was used for allocating IP addresses and creating
NetworkInterfaces. The new code is more suitable to the new DB schema
where each network may have many IPv4 subnets and each subnet may
have many IP pools. Also, the new functions are using prefetch related...

cyclades: Make API server tests pass

Refactor Cyclades code so that it follows the new models for Networks,
Subnets and IPAddresses. This refactor is not complete. Instead is the
necessary refactor for making tests for server API calls succeed.

cyclades: Use NIC UUID in firewall tags

Use NICs UUID instead of index to generate firewall tags. Make the
'set_firewall_profile' action to take the NICs ID as argument. Also,
update the firewall settings.

cyclades: Use Ganeti NIC UUIDs

Since Ganeti 2.8, it is supported to refer to devices (NICs and Disks)
not only by their index but also by their name or UUID. This commit
updates Synnefo to refer to devices by their name. Synnefo will set the
name of the devices which will be a UUID. We do not use Ganeti's UUIDs...

cyclades: Return the newest vm object upon creation

The server_command decorator commits the just created object and retrieves
it back from the database. Return the latter, because the former is stale
in memory.

cyclades: Helper function for commissioning

Create 'quotas.handle_resource_commission' function for handling
commissions for VMs and Networks.

cyclades: refactor server creation command

Split the server creation command in more steps in order to be
decorated with the 'server_command' function and follow the logic of all
other server commands. The main change is that the commission job is not
accepted when the VM is stored in DB, but when the OP_INSTANCE_CREATE...

cyclades: Store action to the VM

cyclades: Add check for net action with no hotplug

In case hotplug is disabled, via GANETI_USE_HOTPLUG setting, network
actions should be allowed only on STOPPED vms. This commit adds this
check and a unittest for this case. Also it makes some other checks...

cyclades: Add 'name' to all commissions.

Make all quotaholder commissions to have a name. Since, Cyclades does
not store the association of a commission with a resource, we include
the resource in the commission name.

cyclades: Support IPv6 only networks

Make Cyclades support IPv6 only networks. Such networks will have
the 'subnet' attribute set to None, in the same way that IPv4 only
networks have the 'subnet6' attribute set to None.

Because currently Ganeti does not support IPv6 only networks, we create the...

cyclades: Fix wrong unit of ram

cyclades: Remove PUBLIC_USE_POOL setting

Remove PUBLIC_USE_POOL setting, since in order to use floating IPs, the
cyclades must be responsible for managing all IP pools.

cyclades: Various fixes regarding floating IPs

Fix some issues regarding floating ips introduced by rebasing branch.

cyclades: Check if network exists in backend

Raise 503 if a user tries to add a floating IP to a VM that resides in a
Ganeti backend that the coressponding network does not exist.

cyclades: Extend /servers with floating IP actions

Extend '/servers/action' API endpoint, to support 'addFloatingIP'
and 'removeFloatingIP' actions.

cyclades: Handle 'EmptyPool' in util method

Refactor cyclades code to handle 'EmptyPool' exception in
'get_network_free_address' function.
