Add filter and filter-out options to suites.

What if, instead of logging a line each time something is matched, we instead log just once each for ```filter_in``` and ```filter_out```? Something like:

```
if filter_in:
    log.info("Submitting jobs that match '%s'", filter_in)
if filter_out:
    log.info("Submitting jobs that don't match '%s'", filter_out)
```

I'm just concerned about adding even more noise to the output.
