Add "MayRunAs" value among other GroupStrategies

Browse Source 
Adds "MayRunAs" value among other group strategies. This strategy
allows to define a certain range of GIDs for FSGroupStrategy and
SupplementalGroupStrategy in a PSP.

This new strategy works similarly to the "MustRunAs" one, except that
when no GID is specified in a pod/container security context then no
GID is generated for the respective containers.

Resolves #56173
