Run a job

We need to attach Go to an Executor in the QIIME SDK so that work can be done by the interface.

This will need to be non-blocking, so we can either get the WSGI server to spawn a new flask process for each request OR, set up a non-blocking process call that we can poll periodically OR, we could create something like SSE to actually push the notification to the interface.
