Report "status" of TransportServer CRD

Title

Report "status" of TransportServer CRD

Description

Currently an end-user cannot tell whether the controller has pushed an update to the BIG-IP device. Ideally the status should report a timestamp that matches the last pushed update. Otherwise it is unclear whether a change has been applied or not.

Actual Problem

From an end-user it is not possible to tell whether a TransportServer has been pushed to a BIG-IP (or whether any errors). This would provide feedback if there is an issue (controller not running and/or BIG-IP unresponsive).

Solution Proposed

Add a Status that can be outputted when running "kubectl get ts -o wide" i.e.

NAME              VIRTUALSERVERADDRESS   VIRTUALSERVERPORT   POOL          POOLPORT   AGE  STATUS LASTUPDATE
my-frontend-crd   10.1.10.82             8080                my-frontend   80         10h  OK     3M

Alternatives

Currently you have to have privileges to look at the logs of the controller to check on status

Additional context

It is not possible to tell the state of a change whether successful or not.

Only the STATUS is still required. @trinaths @mdditt2000 please file JIRA for upcoming sprint.
