* refactor(notifications): isolate endpoint service
Following the ongoing effort to isolate behaviours into their own
packages and off of kv.Service, this change move the notification
endpoints service implementation into its own package. It removes the
endpoint behaviors from the kv service completely.
* chore(influxd): wire up the isolated check service in place of kv service
note: tests are seriously borked here. Cannot reuse any existing testing
as the setup is very particular and the http layer doesn't suppport everyting.
that being said, there are goign to be implicit testing in the
`launcher/pkger_test.go` file. This feels broken, and probably needs to be
readdressed before we GA a 2.0 influxdb....
