kpm diagnostic tool includes wrong log files in case of remote KB server

[reshmabidikar]

The kpm diagnostic tool includes the log files from the path /var/lib/tomcat or the path specified via the --log-dir directory from the local machine on which the kpm diagnostic tool is run. If KB is running on a different server (specified via the --killbill-url) the log files from this remote server (and not the local log files) should be included.
