need REST interface to retrieve execution ouput

[gschueler]

Currently the GUI is the only way to get the output(log) of the execution of a job or ad-hoc. But the rest API does not have this. Please provide a REST api to get the execution output. Something similar to /execution/follow/[ID]

There are a few ways to format this data: it could be structured with metadata in xml, json or yaml. otherwise it could be simply the text output (without metadata).

there have been requests to allow a way to follow along with a running job (e.g. stream output back to an API client) however this could be achieved the way the GUI does it by periodic requests for a new set of data. So I think the basic API output should support offsets (e.g. linewise), as well as requests like "give me the last 20 lines of data" which may not be complete, but it is up to date.

"Download" output link in execution view pages produces only "null" instead of log messages
