Perform allocations in separate transactions

Add ForUpdateManager to the Backend model, in order to guarantee
exclusive order when allocating a VM.

Use manual transactions when allocating Backend and public IP for a new
VM, since these allocations need exclusive access (SELECT..FOR UPDATE)...

Fix race conditions when updating network objects

Use for_update() object manager in order to exclude race conditions
when updating network objects.

Refactor IP pools

Treat IP pool the same way as bridge and mac-prefix pools. The pool is
removed from the Network table and moved to an IPPoolTable containing the
IP pools for all networks. Also added support for external reservations.

Migration files for transfering the pool to the new tables are included....

Unique mac-prefix only for mac-filtered networks

Refactor bridge and mac-prefix pool tables

Redesign the implementation of pools and map mac-prefix and bridge pools
to that design.

Each pool type is mapped to a table in the database, and each row of
that table is a pool of that type. All pool tables must contain the...

Implement multiple public networks

Implement multiple public networks in order to support:
- different public networks per backend
- non-consecutive IP ranges in each backend

To support this, public networks are treated different from private
ones. Namely, they are correlated with one backend (and so have...

Do not allow creation of two big/small networks

- Networks smaller than /29 are not supported in Ganeti.
- Big networks will result in degraded performance in Ganeti
and DB due to the big reservation map.

Implement MAC Prefix Management

In order to guarantee uniqueness of MAC address accross all backends,
synnefo assignes a unique mac prefix to each network in each backend.

A mac-prefix of 20 bits, which is picked from the MacPrefixPool, is
assigned to each Network. The mac-prefix of the network in each...

New management command for creating a network

Create a management command for creating networks. Also remove
the initial_data.json, since it is currently not necessary.

Update servers/networks responses for new API

- 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

Simple per user quota mechanism for networks/vms

- New dict setting VMS_USER_QUOTA to allow setting per user quota
(overrides MAX_VMS_PER_USER setting)
- Private networks quota mechanism (based on MAX_NETWORKS_PER_USER and
NETWORKS_USER_QUOTA settings)...
