Allow multiple sections

[gjohansson-ST]

Proposed change

Allow us to use multiple sections e.g. the user can add/remove sections from the same configuration.
See frontend PR how it would be displayed for the user.

Example of integrations that could use this (some already in UI)

• bayesian (observations list)
• filter (as filters)
• compensation (data points)
• template (alarm_control_panel/lock define the different arming/lock options).
• scrape (sensors)

Please provide an overview of use cases and existing integrations that can use the new selector config, besides the compensation integration.

I have updated the PR description with some integrations that could use this. There are probably also quite a few more than could use it, if it was available when it went into UI.

I'd say that of the ones mentioned now, only bayesian, compensation and filter are suitable. Scrape would use sub entries (nuggets), and template alarm control panel I don't see how it would use a multiple section. There's only one action (script) allowed per alarm control panel service action and panel and we use action selectors for that.

I was more thinking the whole arming definition would go into sections. So instead as currently you need to ask which ones to use and present on a second form. The user could just simply add one after the other and define for which action it is.

So I think that would also be the same for lock, cover etc.

arm_away:
  action: alarm_control_panel.alarm_arm_away
  target:
    entity_id: alarm_control_panel.real_alarm
  data:
    code: !secret alarm_code

[MartinHjelmare]

What's the second form? Is it really intuitive to use sections when there's a limited set of distinct items to configure?
