Integration of Neutron NSX plugin working with KVM

Feature Lead: Andrey Danin
Design Reviewer: Vitaly Kramskikh, Andrew Woodward
Developers: Igor Zinovik
QA: Igor Zinovik

In order to communicate with NSX cluster we need to install to the Slave nodes 'NSX bits' packages which allows us to consume virtual tunnels to the NSX cluster. Also we need credentials for NSX cluster to register the Slave nodes in it and to provide the credentials to the Neutron NSX plugin.

Because there is no tasks in Naulgun/Astute now to check credentials, download packages and create some kind of repo with them, we assume that downloading of 'NSX bits' will be done by Puppet, and no credentials verification will be provided in current implementation.

Limitations:
current implementation does not support installation and configuration of NSX appliances.
current implementation assumes KVM hypervisor for Nova Compute
current implementation assumes 'NSX bits' packages must be located on any Web server which should be reached by Slave nodes during Puppet run

Prerequisites:
NSX cluster is up and running
NSX parameters are known
Web server that hosts NSX packages and does directory indexing. It must be accessible by slave nodes.

Features to implement
Specific configuration of OpenVSwitch
Neutron NSX plugin configuration
Disable L3 agent
