Separate OS startup from Software startup tasks #4

Open vtgreybeard opened 2 weeks ago

With no docker we need to rethink how the system and service startup work. The environment persists now, so we must validate settings and configs, and no longer need to create all structures everytime.

Old process: a3init

expects ADS & ODS to be pre-mounted outside of Docker
creates all folders & permissions
starts all service daemons
preps DBs from ADS, rehydrates manager.db
starts engine (java)
enables webUI

New process: Boot: a3.startup

sets up all /tmp structures, launches long running scripts (metrics)

ADS Mount: dsMount

mounts ADS from user script (or checks for pre-mounted)
preps DBs and system settings from nimbusDB

Alike Start: startEngine

inits java & fuse runtime
