Get rid of unnecessary DIC reconcile updates (#2294)

Browse Source 
* Get rid of unnecessary DIC reconcile updates

Also fixed status.lastExecutionTimestamp to be the last polling time
as intended in the design, and not the last reconcile update time.

Signed-off-by: Arnon Gilboa <agilboa@redhat.com>

* Pass DIC last execution time by annotation
