[7.5] [Telemetry] change of optin status telemetry (#50158) (#50608)

* initial push

* self code review

* ignore node-fetch type

* usageFetcher api

* user agent metric

* telemetry plugin collector

* remove extra unused method

* remove unused import

* type check

* fix collections tests

* pass kfetch as dep

* add ui metrics integration test for user agent

* dont start ui metrics when not authenticated

* user agent count always 1

* fix broken ui-metric integration tests

* try using config.get

* avoid fetching configs if sending

* type unknown -> string

* check if fetcher is causing the issue

* disable ui_metric from functional tests

* enable ui_metric back again

* ignore keyword above 256

* check requesting app first

* clean up after all the debugging :)

* fix tests

* always return 200 for ui metric reporting

* remove boom import

* logout after removing role/user

* undo some changes in tests

* inside try catch

* prevent potential race conditions in priorities with =

* use snake_case for telemetry plugin collection

* refactors needed to extract cluster uuid based on collection

* refactoring uuid getters

* revert unneeded changes from merge

* finish server/browser fetching

* skip a test  :(

* skip handle_old

* merge master

* fix failing tests
