Parlour integration

Not yet for commit.

This how I anticipate the integration working, I'm just not sure the best way to make sure the sqoop job is used as a dependency yet.

I can pass in a tap/source to the Import/ExportSqoopJob, but I'm not entirely sure how scalding will match it up with what gets used in the load.

hm.
We just need to remember to do the archiving here as well
