Address the TOCTOU when generating random names by having at most 10
attempts to assign a random name when creating a pod or container.

[NO TESTS NEEDED] since I do not know a way to force a conflict with
randomly generated names in a reasonable time frame.

Fixes: #11735

Had to move the loop for container creation around CreateContainerStorage. Having it inside broke the user NS tests for reasons I did not understand.

@mheon PTAL. Restored the old function and turned it into endless loops to be consistent.
