            Log:
            test if nfs-server-generator can create/control its UDP sockets

After introducing the systemd_nfs_generator_t domain, a bug report was
filed which revealed that SELinux prevents the nfs-server-generator
from creating and controling its UDP sockets. The TC reproduces the
situation.

In order to support all functions of the nfs-server-generator program,
I believe that SELinux policy should allow these actions. The TC looks
for appropriate policy rules and file context patterns.

The TC covers RHEL-111556.
