Refactor the "os availability zone list" command to make it a common command instead of a compute-only command. Since availability zones are common to compute, volume and network (new), this refactoring allows availability zone support to be added for volume and network. In addition to the refactor, unit and functional tests were added. Change-Id: I63e9d41d229b21cd38e5a083493042c096d65e05 Partial-Bug: #1532945
