Automatically convert URLs in values into links in the dashboard

[JamesNK]

Description

Automatically convert URLs in values and properties into links:

GridValue is used in many places:

• Resource properties, structured logs properties, span propertries
• Env vars
• Message on structured logs grid

There is a limitation: it doesn't work together with highlighting. Highlighting is only supported over plain text, not HTML. That means links are disabled when you begin searching with a filter and you go back to the current experience.

Getting these two features to work together properly is quite tricky. Will require building up a model of the text and transforming it when applying different operations (adding in links, adding in highlights)

Addresses #6175
Fixes #4845

This is an impactful change with some risk. Post 9.0 feature.

[JamesNK]

Please take another look. I came back to his and did some more testing and noticed that content wasn't properly HTML encoded. Required a change in order of operations when parsing logs and content.

Please hold off on merging this for a day as I'm looking at #6230 today for 9.0 and will want to backport it. There's overlap here which would make that backport difficult/risky.

Looks like we don't use captured groups here, so we could add RegexOptions.ExplicitCapture to allocate less when matching, now that we've added a group.

[JamesNK]

I looked at this regex more and I removed the group. I added flags to ignore case and culture.
