If this grep doesn't match, the task returns a failure and it causes
the job to abort with POST_FAILURE. I think more info is generally
helpful and you can always grep "netstat" on the file manually; thus
remove the grep to avoid suprious failure.

A recent magnum bug (https://storyboard.openstack.org/#!/story/2008494)
when running with uwsgi has yielded an interesting question if Ironic
is orphaning rpc clients or not. Ironic's code is slightly different
but also very similar, and similar bugs have been observed in the past
where the python garbage collection never cleans up the old connection
objects and effectively orphans the connection.
So we should likely at least try to collect some of the information
so we can determine if this is the case in our CI jobs. Hence this
change and attempt to collect that data after running CI.
