[ML] Change close job api to no longer extend from TransportJobTaskAction. 

The execution has diverged too much from post data, flush and update process apis, since the close all jobs have been added.
The logic is now easier to understand as it exist in a single source file instead of in both CloseJobAction and TransportJobTaskAction.
