Add visibility for new releases and possibly update Powerwall dashboard from Grafana UI

[wreiske]

I have been using https://www.percona.com/software/database-tools/percona-monitoring-and-management to monitor a few hosts. Something interesting that it includes is the ability to update the dashboard directly from inside the dashboard.

My thoughts would be to check https://api.github.com/repos/jasonacox/Powerwall-Dashboard/releases/latest against the local running version and display if there is an upgrade available. I'm not sure how we'd be able to run the ./upgrade.sh from inside the docker container to upgrade directly in the UI, possibly a named pipe.

Interesting! Thanks @wreiske . Please explore and let us know if you are able to solve it. I'll tag this as an enhancement backlog item.
