Docker related issues

[goodoldme]

I have a couple of minor docker issues everytime I upgrade.

1. influxdb container does not have the user: "${PWD_USER:-1000:1000}" specified in powerwall.yml. Not sure if this is by design. This is causing all files being created as root, which in turn causes my backups to fail.
2. I run Powerwall-Dashboard in a separate docker network (powerwall-net).

I manually update powerwall.yml to fix these after an upgrade. Wondering if there's a better way to do this
