sentinel

[0trust3r]

• "sentinel" implementation-> we need some way to kick off all the various tram processes &monitor/re-kick if any of them fail

talks to the tram operator only

sentinel restarting of failed procs and restarting the procs when needed

scope of this should be small ideally

after a good discussion with @trustlesscode , I think I might like the name sentinel more than manager
