Could we move all these into the Calendar driver

drivers/drivers/place/calendar_common.cr

Lines 231 to 240 in 4107204

	# NOTE:: GraphAPI Only!
	@[PlaceOS::Driver::Security(Level::Support)]
	def get_user_manager(user_id : String)
	logger.debug { "getting manager details for #{user_id}, note: graphAPI only" }
	client do |_client|
	if _client.client_id == :office365
	_client.calendar.as(PlaceCalendar::Office365).client.get_user_manager(user_id).to_place_calendar
	end
	end
	end

There are already graph api only functions in there - we don't want to manage secrets on multiple drivers
