[Hps] clashps to hps migration

[Nathan Baltzell]

Hi Everyone,

JLab's CC is now ready and willing to migrate clashps account to hps.
In addition to changing user/group, this is going to include renaming
the following directories:

/home/clashps 
/home/hps

/work/clas/clashps
/work/hallb/hps

/volatile/clas/clashps
/work/hallb/hps

(/mss/hallb/hps will not be changed)

For work/volatile directories I will ask if we can temporarily leave the
old ones to minimize disruptions for users. 

This has been discussed in HPS software meetings and listserv, and I would
like to give CC the green light to make this migration tomorrow.  If you want
to hold off on this until later, let me know.

Regards,
Nathan
