orchestration: tolerate NotFound in wait_for_stack_status

When waiting for a stack to transition to DELETE_COMPLETE status
it's possible to either get that status, or a NotFound exception
so catch the exception and return in that case, to avoid needing
try/except around the wait, or risking races in tests which wait
for DELETE_COMPLETE without a try/except (test_volumes.py)

Make javelin2 create_server wait for server to boot

Creating a server is a asynchronous command, make create_server wait for
the server to go to 'ACTIVE' state so we can run a check on the server
afterwards.

This also helps address the issue where the server isn't in ACTIVE yet
and grenade moves on and turns off nova-compute causing the server to go
to ERROR state.

Make javelin2's ping for longer

Since as far as I can tell ping doesn't have a good way to ping until it
gets a response or until x seconds pass, use a python loop to do it
instead.
