Simplify update of license files to all servers with HMS.
Per email:

It would actually be very cool to be able to drop license files into
a secure folder, that would allow HMS to act like a license server...
not in a P4AUTH way, but the server would be automatically renewed
based upon dropping a file in there.

Commonly with SDP deployments, licenses are versioned in
/p4/common/config/licenses, and that folder is sync'd to all hosts
with sdp_sync.sh. That 'licenses' folder hasn't been documented
and enshrined as a formal SDP standard yet, but that can be done as
part of implementing this.
