[SRU] Please SRU MAAS 2.0 (final) into Xenial

[Andres Rodriguez]

Following the SRU of MAAS 2.0rc2 (LP #1599523) in Xenial, we would like to request the SRU of MAAS 2.0 Final.

[Impact]
This is a new version of MAAS that provides bugfixes only. It addresses various upstream bugs, that were fixed after RC2 was released (and before it landed in Xenial).

[Regression Potential]
Minimal. MAAS has been thoroughly tested stand alone as well as via upgrades. It has been QA'd in a CI lab as well as other production deployments:

Tests done:

1. Upgraded a production lab.

2. MAAS CI Lab:
 - Tests Installation (from pkgs), configuration / customization of MAAS, enlistment, commissioning. It also tests deployments with Juju.
 - Tests various API's
 - Tests are performed against Xenial

3. Other manual testing include:
 - Installation (both fresh and upgrades)
 - Configuration
 - Taking nodes through the lifecycle for regression testing.
 - Custom configuration to ensure proper operation.
 - Tests API's for regressions, and keeping backwards compatibility.
