Allow setting the supervisor to a "local mode" which stops apps and prevents cleanup

Browse Source 
A RESIN_SUPERVISOR_LOCAL_MODE variable is introduced. When this variable is "1", all apps
are stopped and the update cycle stops executing changes other than deviceConfig changes
and the proxyvisor.
