Description

Currently we can specify the unique Yarn Service app name in the "yarn app" command to fetch the status and to perform various operations.

It will also be useful to specify just the app name in the "yarn logs" command. This will be more convenient that getting the app id of the service, just to fetch the logs.

An example usage is as follows:

yarn logs -service sleeper-service
