Extend NetworkInterface model with a dirty bit, indicating whether
the index of the NIC is consistent with the one in Ganeti. This flag is
set when deleting a NIC, and is switched off after processing the
notification from Ganeti. Removing a NIC with the dirty bit on is not
allowed.

Raise Overlimit exception when either bridge or mac-prefix pool
is exhausted. Also prohibit public network creation.

- Handles nic connections instead of vms. New NIC model and NICs
  collections created to handle the NIC api logic. NIC models get
  updated on each vms/networks api call.
- New private network creation form.
- Display additional fields on private networks list (cidr, nic ip)
- New cyclades ui settings introduced. UI_NETWORK_AVAILABLE_NETWORK_TYPES,
  UI_NETWORK_AVAILABLE_SUBNETS, UI_NETWORK_ALLOW_DUPLICATE_VM_NICS,
  UI_NETWORK_STRICT_DESTROY.

check available network status options based on Network.OPER_STATES

Set the VM deleted flag when receiving a failure notification for a
Ganeti OP_INSTANCE_REMOVE operation, even if the VM operstate is not
ERROR. The server may not exist in the backend not only because the
creation failed, but also because a remove notification was lost.

This reverts commit 5d40a128fb593ed641400c462f0e00a1b457f76e.

- Reponses for servers and netowrks details (list or solo) are now
consistent to recent backend changes.
- Methods get_nic_from_index and construct_nic_id have been created
- Syntax for nic removal from network/vm has been adjusted

During handling of ganeti-op-status messages, state was set to error
only if the the opcode was OP_INSTANCE_CREATE. This resulted to
vm's never being deleted, if they did not exist in Ganeti.

- Fix bug in backend_add
- Display backend_name in network_inspect command

None tags in gnt-network create does not validate.

Set as available in the pool the bridge and mac prefix that was
used by the deleted network.

Create a new model, to represent the state of each network in each
backend.

Since Ganeti version 2.6, Ganeti is aware of private networks. We take
advantage of this by propagating network handling to Ganeti. Network
model is expanded to include information about the type of network
(public routed, physical vlan, private filtered), subnet, gateway, dhcp,
link and mac_prefix.

- Update Network Model and delete NetworkLink model
- Create MacPrefixPool and BridgePool models
- Default constant settings for MacPrefix management

New module implementing instance allocation to one of the available
backends. Allocation is performed based on memory and disk utilization.
Statistics for each backend are stored in DB and updated periodically.

Allocation can be customized by creating a new allocation strategy
and declaring it in BACKEND_ALLOCATOR_MODULE setting.

- Create command to create a backend (snf-manage backend_create)
- Create command to modify a backend (snf-manage backend_list)
- Create command to list backends (snf-manage backend_modify)
- Modify listservers command to display the backend that hosts the VM

Replace use of global RAPI client, with the cached client from the
VirtualMachine or Backend model.

Dispatch network actions to all backends.

- Create Backend model holding info about credentials, status and resources
- Add Backend as foreign key to VirtualMachine
- Create a cache of Backend clients (RAPI) for better performance
