Add new script to notify users when they are over their quota. Runs from

cron daily, on the fs node (ops) as root. Uses lots of configure variables
so that it does the right thing in any installation, without any
customization.

One possible caveat regarding quotas: If FS_NODE != USERNODE, they don't
have a login on the fs machine. So checking their quota won't work unless
the rpc.rquotad(8) daemon is running on FS_NODE, which we currently don't
do.

In order to do this right, I had to add a new configure var,
FS_WITH_QUOTAS, that has a space separated list of file systems that have
quotas enabled. (Ie the default is 'FS_WITH_QUOTAS="/q /users"'.) It
doesn't have any default, since I couldn't come up with a reasonable one.
All the defs files have been updated appropriately to define this new
variable.

+Subject: over disk quota at @THISHOMEBASE@
+
+Hello,
+
+It looks like your disk usage has exceeded your disk quota. Please move or
+remove some files to get below your quota. Disk space is limited, so if
+you could clean up your directory it would be appreciated.
+
+You can check your usage with the 'quota' command on @USERNODE@:
+
+> quota -v -l
+`quota -v -l $i`
+
+The directory trees where you most likely have files are:
+Project directory:    @FSDIR_PROJ@
+Group directory:      @FSDIR_GROUPS@
+User/Home directory:  @FSDIR_USERS@   
+
+Thanks,
+@THISHOMEBASE@ Testbed Operations
+@TBOPSEMAIL_NOSLASH@
