Need to capture user that created and updates a Release

For improved tracking a audit purposes we need to capture when a user creates a new Release, updates an existing Release or deletes a Release.  Currently, there is no way in the database or logs to find this information.

We need two areas to capture this information:

1. In the "releases" table, capture the user that initially created the Release.
   1. Also, display this information in the Manage Release dialog in the UI of Zephyr Enterprise.
2. In the "audit_logs" table capture when a Release is created, updated or deleted with the user that performed the associated action.
   1. Currently, only when a Release is cloned is anything captured.
