Dynamic tunnels (#579)

## Description:

Update deployment:

1. automatically create and configure CF tunnels and point it to
subdomain.domain

2. Send loki logs to remote endpoint

3. create metric-exporter.sh to push prom metrics to remote endpoint

4. update and refactor deployment & env variables

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
