This plugin will report JS deprecations to the server and increment prometheus metrics. It's designed to help hosting providers roll out breaking changes.
Requires the discourse-prometheus plugin to be installed.
Metric will be created with the name discourse_js_deprecation_count, and with two labels:
dbindicates the relevant site in a multisite clusterdeprecation_idis the id of the discourse/ember deprecation
For a deprecation to be labelled correctly, its id needs to be added to the list in lib/deprecation_collector/list. Any unrecognised deprecations will be tracked against id=_other.
