Give logfiles "short" names

[nbastin]

Would be nice if we could give logfiles a short name in the dropdown, which might more accurately reflect what it is to the user when you are aggregating logs at a remote log store. Something perhaps like:

files:
 - shortcut: 'TL-SG2424 A'
   logpath: '/mnt/log-store-data/rsyslog/172.31.0.1/syslog.log'
