* Dashboard: Add named capture groups to variable query regex
Variable query regex are able to use 'text' and 'value' named capture
groups to allow for separate display text to be extracted from the
query result. e.g.
Using a regex of /foo="(?<text>[^"]+)|bar="(?<value>[^"]+)/g on a query
result of metric{foo="FOO", bar="BAR"} would result in the variable
value being set to 'BAR' but display text being set to 'FOO'
Resolves#21076
* Improve regex capture group documentation
* Update docs/sources/variables/filter-variables-with-regex.md

* Use text capture if value capture does not match
This is to keep the behaviour consistent with the current behavior. See
discussion https://github.com/grafana/grafana/pull/28625/files#r516490942
* Improve regex field placeholder and tooltip message
To make the feature more discoverable to users the place holder example
now includes the named capture groups. The tool tip message also
includes a reference and link to the documentation.
