restructure run scripts as micro-services

[ahdinosaur]

restructuring the app to support individual instances has led me to make the app easier to run as a set of micro-services (it's a long story). this is part of me trying to clean up known hacks and stop myself from implementing more hacks, i don't intend to create the perfect micro-service system just something that works with what we have now. anyways, here's an issue to track progress. :game_die:

• [x] server.js
• [x] services
  • [x] api-service
  • [x] ui-service
  • [x] bundle-service
  • [x] assets-service
  • [x] less-service
• [x] setup pm2 processes.js file
• [x] setup bin/holodex to use pm2

yeah nah, actual micro-services are too much of a change that we don't need so it's just gonna be psuedo micro-services that run under pm2 as a single service within our existing dokkus. still nice to clean this up though.
