Added new controller which allows the following: - add tag to the server - replace set of server tags with new set of tags - get list of tags for server - check if tag exists on a server - remove specified tag from server - remove all tags from server Functional tests and annotations "@wsgi.Controller.api_version(*)" for controller methods will be added in next patch with creation of new API microversion. APIImpact Implements: blueprint tag-instances Change-Id: Ibc44228aeae94c17353af7fccfcfb2c11b2e9190
