Re: [libvirt] [Libvirt-test-API][PATCH] Add a pair of keywords in parser.py for supportting testcases loop

To support test cases loop in config, adding a pair of keywords
"start_loop", "end_loop" follows loop times.

For example:
-----------------
domain:start
     guestname
         vm1

domain:save start_loop
     guestname
         vm1

domain:restore end_loop 10
     guestname
         vm1

domain:destroy
     guestname
         vm1
-----------------
