## 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: <DISCORD USERNAME> --------- Co-authored-by: Evan Pellegrini <evan@Evans-Air.attlocal.net> Co-authored-by: evan <openfrontio@gmail.com>
