about 10-20% of times smoketests were using this script to ensure availability
of services, the smoketest failed after the script succeeded. This change
improves the script by:

* providing an early exit for already deployed services without testing
  multiple times for success if the first test succeeds
* raising the amount of successful checks needed to 25 and sleeping a second
  after each successful test in order to lower the probability of the service
  not being available for the smoketest after the script succeeds.
