Stop occupying threads during retry phase

Before this change, the retry mechanism was implemented in the
way that instead of having a queue with an async executor,
there is a loop with sleep which causes the current thread to block.
This causes threads starvation on the forwarder site and brings down
the Gerrit node. Removing the loop and rescheduling the entire task
allows to unblock the thread and queue the retry which solves the
starvation issue.
