Based on our experience with Firefox for Android, annotating Glean metrics with issue tracker component information can provide valuable context to anyone searching for metrics. This adds a new set of tags corresponding to the components in the tree, annotates the existing Glean metrics. Finally, it also adds a new mach command called `update-glean-tags` to update the tags files based on build metadata. Differential Revision: https://phabricator.services.mozilla.com/D134332
