Split out services into their own Cloud Runs

[MarkEdmondson1234]

Managability wise:

• [x] Webapp
• [x] Slack
• [ ] Discord
• [x] Dreamer
• [x] Pubsub
• [x] Gchat
• [ ] Email
• [x] Encoder service
• [x] Document chunker
• [x] QnA service

All could have their own URL, no need to be in one monoapp. Maybe move some to Cloud Functions too

For very big files, encoder/chunker as its own service is needed else it gets stuck in loop
