Deploy on AWS with at least 2 stages about yet-another-better-office-hour-bot

Get bob ready for aws deployment in the future

Already on AWS

Manual deployment is quite error prone, we will need to setup at least a beta stage and a prod stage and CI/CD

[KaoushikMurugan]

we could try to use this to do it maybe? We already have scripts to copy files and there is only one sequence of commands we use to deploy the bot on aws (ssh, then pm2 stop , and pm2 start)
