Deploy watcher -api as wsgi-app under apache

[aditi sharma]

In accordance with OpenStack community goal Watcher needs to meet the goal to deploy api through WSGI under any performant web server (apache/ngnix). We need to add wsgi app and apache template to watcher and we also need to update devstack plugin to default deploy watcher-api with apache.
