Make grafana plugins to survive a restart

[lldaedalusll]

Problem/Motivation

I am using the clock plugin in grafana. With each grafana addon restart I have to reinstall that plugin.

Expected behavior

The plugin remains installed even after restart.

Actual behavior

All plugins are gone after a restart.

Steps to reproduce

• install Clock plugin in grafana addon
• restart grafana addon
• notice that clock plugin is no longer installed

Proposed changes

This is propably down to docker directory mapping / sharing / forwarding. I am no expert here, so I can't make suggestions. But I expect that there most propably is a plugin directoy which needs to allow changes to become persistent over addon restarts.

This is actually done by design, if an update causes issues (for example, could be anything else) that causes problems, you'll be able to remove it from the configuration.
