Wait for the DC to get into the S_IDLE state. This should be
invoked only after a CIB modification which would exercise
the PE. Parameter "what" is whatever the caller wants to be

It is assumed that the DC is already in a different state,
usually it should be either PENGINE or TRANSITION. This
assumption may not be true, but there's a high chance that it
is since crmd should be faster to move through states than
this shell.
Further, it may also be that crmd already calculated the new
graph, did transition, and went back to the idle state. This
may in particular be the case if the transition turned out to
be empty.
Tricky. Though in practice it shouldn't be an issue.
There's no timeout, as we expect the DC to eventually becomes
idle.
