SOL003 specification allows oauth token based authentication between the client and server. 

This story will enable using oauth from the VNFM adapter to the VNFM including adding oauth token handling in the VNFM simulator.

The VNFM adapter will use the username/password for the VNFM in AAI as the credentials for requesting a token from the VNFM. Oauth will not be used if no username/password is defined in AAI for the VNFM .

A spring profile will be used to turn on oauth in the simulator
