[FLOC-727] Design sketch of restart-policy handling.

https://clusterhq.atlassian.net/browse/FLOC-727
"If it fails enough times, an ``Application`` ..." would be correct.  This is a comma following an introductory prepositional phrase.  The comma is not required in this case but it's widely accepted.

Flipping the sentence structure around to put "If it fails enough times" at the end means it is no longer an introductory prepositional phrase (it can generally only be introductory at the beginning of the sentence) and the comma becomes incorrect.

:smile_cat: 

Also, elaborate on "enough" - presumably this is either >retry count or >=retry count.
