Use relative aliases for all non-current Grafana aliases (#60062) 
* Use relative aliases for all non-current Grafana aliases

Prevents non-latest documentation "stealing" the page away from latest
and through permanent redirects for latest pages that no longer exist.

The redirected pages are indexed by search engines but our robots.txt
forbids them crawling the non-latest page.

Breaking changes

Constant variables

In order to minimize the confusion with Constant variable usage, we've removed the ability to make Constant variables visible. This change will also migrate all existing visible Constant variables to Textbox variables because which we think this is a more appropriate type of variable for this use case. Issue #29407

Plugin compatibility

We have upgraded AngularJS from version 1.6.6 to 1.8.2. Due to this upgrade some old angular plugins might stop working and will require a small update. This is due to the deprecation and removal of pre-assigned bindings. So if your custom angular controllers expect component bindings in the controller constructor you need to move this code to an $onInit function. For more details on how to migrate AngularJS code open the migration guide and search for pre-assigning bindings.

In order not to break all angular panel plugins and data sources we have some custom angular inject behavior that makes sure that bindings for these controllers are still set before constructor is called so many old angular panels and data source plugins will still work. Issue #28736

Deprecations

Query variable value group tags

This option to group query variable values into groups by tags has been an experimental feature since it was introduced. It was introduced to work around the lack of tags support in time series databases at the time. Now that tags (ie. labels) are the norm there is no longer any great need for this feature. This feature will be removed in Grafana v8 later this year. Issue #30160
