PXE Servers / Images: render tables consistently with the rest of the ui

We'll use shared/summary/textual to render the table rather than
creating the whole table row by row, column by column manually.

Automate - Service check_provisioned method change.

Service provisioning was not waiting for all of the child provisioning
 to finish.  It was waiting only until the child provision(s)
advanced past the check_provision state which would have had a
provision state of 'provisioned'. The very last step of the state
machine sets the state to "finished".  This method change forces
the service task to wait and retry until all of the children
state machines are completely "finished".
