cyclades: Make (network, ipv4) unique for each NIC

Add a unique constraint to NetworkInterface model. This constraint
asserts that the same IPv4 address from the same network will no be
assigned to more than one NICs.

cyclades: Extend Backend model with disk_templates

Extend 'Backend' models with 'disk_template' attribute, that contains
the list of disk templates that are available in each backend.

cyclades: Import settings from django.conf

cyclades: Add migration file for IPv6 networks

cyclades: Add 'drained' flag to Network

Extend Network model with the 'drained' attribute, to indicate whether a
network should be used in public IP allocation when creating servers.
This option is only useful for public networks.

cyclades: fix db migration

Migration 0066 should not run on a fresh installation.

Refactor QuotaHolder serial model

• Merge 'accepted' and 'rejected' field to 'accept' field.
• Add 'resolved' field, indicating whether this commission has been
  accepted/rejected to Quotaholder
• Remove custom save() method. Handle 'pending' field manually....

Create public NIC when creating VM

Until now, a server's public NetworkInterface was not created in the DB
until the arrival of the message from Ganeti hooks. However, the IPv4
address of the NIC is reserved before sending the OP_INSTANCE_CREATE
job to Ganeti....

Add migration file for quotaholderserial

Merge branch 'ui-0.11' into devel-0.12

Merge remote-tracking branch 'origin/devel-0.12' into ui-0.11

Reapply diagnostics migrations

Do not create bridge for public network

Change and fix migration files

Change network migration, so that it does not allocate a new bridge to
existing network. Instead it keeps the bridges from the old NetworkLink
pool.

Remove network_mac_prefix migration because there are no networks with
mac prefixes....

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....

New method for creating BackendNetwork entries

Create a new method to the Network model, in order to create the
BackendNetwork entries tha correspond to this network. Also remove
the custom save method, since when multiple public network will be
supported, we want them to be correlated with specific backends.

Fix bug in migration file

Do not allocate a bridge from the pool for deleted networks.

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...

Fix bugs in migration files

Add support for IPv6

- Extend the Network model with fields for holding the IPv6 subnet and
gateway.
- Update network API methods.
- Modify ganeti hooks to return IPv6 address for all network interfaces.
IPv6 is now derived from the IPv6 subnet of the network in Ganeti,...

Encrypt Backend password

Use cipher to encrypt the passwords of the Ganeti backends in the DB.
Encryption/decryption is based on a configurable key, defined by the
ENCRYPTION_KEY setting. After modifying this setting, synnefo will be
unable to decrypt already stored passwords, and passwords must be...

Print warning about subnet value during migration

Major modifications to Network model

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,...

Create Backend model to represent a ganeti backend

- 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

New migrations for cyclades-app

Fixes some flavor constrains issues

Renumber the migrations

Update the Flavor's unique_together constraint

A DB migration is required.
