Code Issues Proposed changes

NSX|P provider networks support

Browse Source 
Supporting provider networks including:
- Creating a base plugin for T & P plugins (separate from V)
- Moving some nsx-T code to the common plugin after stripping
  it from v3 specific code
- Reusing the nsx-T DB table for keeping the provider network
  configurations
- Support for vlan transparent
- Support for update network action

Also adding unit tests for provider networks and enabing tempest
tests for networks
