Add ability to go from a selected item in a visualization to Discover

[kohlmanj-hs]

Describe the feature:
Our users would like the ability to be able to click/hover on an "item" in a visualization and click something and be taken to a Discover window with a filter for the item field name and value. A couple of examples:

Describe a specific use case for the feature:
Given a visualization:

• using metricbeat-* index pattern , but should apply to any index pattern
• it shows a timeseries of CPU for kubernetes nodes
• presumably this could apply to any visualization type, Pie Chart, Line Graph, Bar Chart, etc.

Action:

• users would like to be able to click on a highlighted item in a visualization and say Open in Discover.
• I could image that when you hover over an "item" in a visualization, currently there are choices for + or - to filter the current visualization or current dashboard. I could image a third choice, "Open in Discover"
• when you get to the Discover window:
  -- it should have pre-selected the index pattern used in the visualization
  -- set a filter for the "item name" and "item value" the user was hovering on.

Alternative example:

• when the user hovers over the highlighted item in a visualization and clicks "Open in Discover"
• it defaults the index pattern to filebeat-*
• sets the filter as described above. In some cases the key might not be in filetbeat, but the code could still open discover as described.

I've seen a number of reasonably similar requests for this type of feature in Git.

I think this can be seen as a sort of duplicate of #122631 , which has been addressed by #125983 and subsequent PRs
