Signed-off-by: Sergey Chvalyuk grubberr@gmail.com

What

Try to fix https://github.com/airbytehq/oncall/issues/598

How

_get_reporting_service method is caching instance of "ReportingServiceManager" for uniq pair (customer_id, account_id)
If we have a lot of such uniq pairs we cache a lot of ReportingServiceManager objects which are pretty heavy.
