Matt Riedemann 901fb45421 Remove lock on SchedulerReportClient._create_client ... This is a follow up to change Idf6e548d725db0181629a451f46b6a3a5850d186 where the compute API started lazy-loading the SchedulerReportClient because of slow startup times, presumably because of the locking when creating SchedulerReportClient. The lock on SchedulerReportClient._create_client is removed since there is no clear indication that it is necessary. It was added in change I02ac615dc26a4a0d1fd28a638f622777e41d14e4 as a precaution: "I've made the _client method synchronized so that in the unlikely event that the resource tracker is trying to do its update job while some other thing is happening, we won't waste the client. This may not be necessary, but probably doesn't harm anything." Long-term we could consider making SchedulerReportClient a global singleton so a TODO is left for that since it would require inspecting cache-sensitive methods to see if a lock is necessary.
