Code Issues Proposed changes

Reduce overhead of stack show loop

Browse Source 
A stack show of the overcloud is an expensive operation because
resolving outputs results in a nested stack traversal. This change
adds --no-resolve-outputs to the stack show loop which is waiting for
the stack to no longer be IN_PROGRESS.

On my undercloud this reduces stack show time from 14 seconds to 3
seconds. Since polling load is lower now, the polling period is
changed to a shorter 10 seconds.
