Split dashboard config & state

[RichiH]

As per IRC with @bergquist and loosely related to #8888 :

It would make sense to split dashboard config (Title, graphs, line width, all those things) from dashboard state (template values, currently selected template value, etc). If the time frame to display is config or state can be debated, but I would lean towards config.

This obviously also ties into #1959 and @bergquist notes that this split would most likely happen after global templates are tackled.

Some more considerations regarding this can also be found in https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

A way to implement that would be to have sub-dashboards, i.e. dashboards able to display inside a dashboard, and re-use the top-page settings (intervals) and variables from the parent dashboard.

This feature request has been open for a long time with few received upvotes or comments, so we are closing it. We're trying to limit open GitHub issues in order to better track planned work and features.

This doesn't mean that we'll never ever implement it or that we will never accept a PR for it. A closed issue can still attract upvotes and act as a ticket to track feature demand/interest.

Thank You to you for taking the time to create this issue!
