Adjust metrics to the new specifications (#5937)

* Add `AnalyticsTransactions` with a set of `TransactionDefinition` items matching those in the user story

* Use that for `AnalyticsLongRunningTransactions`, make sure we send the right fields (name, operation, description)

* Add `AnalyticsSendMessageWatcher` to track how long it takes for an event to be sent and for us to get a call back for that from sync

* Add `Noop` implementation for enterprise
