jx logs to be able to tail a pipeline run log?

[jstrachan]

we have a command jx logs foo where foo is the name of a Deployment and it tails the log.

It would be nice to have a similar command to tail the logs of a jenkins job run.

I wonder if we should reuse logs but allow a prefix on a name? e.g.

# tail the logs of a deployment
jx logs foo

# tail the logs of a build run
jx logs pipeline/foo
jx logs pipeline#4
