Prometheus: Add disableRecordingRules datasource config

[shantanualsi]

What is this feature?

This PR introduces a config to the Prometheus data source that optionally disables recording rules. It is by default set to false so that existing users of the plugin resort to the default behaviour as before.

Why do we need this feature?

The Prometheus recording rules can be expensive for some instances. This PR adds an optional configuration disableRecordingRules to the Prometheus data source.

Who is this feature for?

Users of prometheus data source plugin

Which issue(s) does this PR fix?:

Fixes #69586

Special notes for your reviewer:
I need some help in making the documentation a bit more specific and useful. I think the snippets that I added to the documentation may be somewhat vague.

Please check that:

• It works as expected from a user's perspective.
• If this is a pre-GA feature, it is behind a feature toggle.
• The docs are updated, and if this is a notable improvement, it's added to our What's New doc.

@lwandz13 Why are we back porting this feature? I think we typically only backport bugs

If this is v10 feature only it needs to be backported to v10 due tot he way the grafana/grafana repo is set up

@lwandz13 that flow chart says no-backport D1=>D2=>T1. See https://raintank-corp.slack.com/archives/C02GTT9D6CW/p1688052585513679 for more info

Code looks good, and things are working for me locally. Thanks for taking a look at this!

Docs is a little different than code in that we support two previous versions of grafana in addition to latest. So we backport all changes that apply to those versions.
Additionally, if you want your changes applied to latest then you must backport to 10.0x because main tracks next not the current docs

@Eve832 while this issue has a docs label, it is a new feature, not just docs updates

Looks like we're hitting an API limit in drone, it resets every hour, I'll rerun the jobs in a bit and get this merged
