Add ManagedProfileLifecycleStressTest#testCreateStartDeleteStable

Browse Source 
Added a similar test to
ManagedProfileLifecycleStressTest#testCreateStartDelete but with
waitForBroadcastIdle after each user operation. This is just a temp
test to identify if adding the sleeps after user operations reduces
flakiness.

Test: atest ManagedProfileLifecycleStressTest
