nebraska: Add a conf file

With this new .conf file (that will be put in /etc/init), we can bring
up nebraska.py with upstart only on test images before update_engine
comes up. This allows us to run some of the AU tests (like interrupt
tests) that currently we can't run (because they need the nebraska be up
right after system startup) and we can't access to device fast enough to
bring up nebraska.py.

Also added a --poll flag to nebraska.py so it can be called by this flag
to wait for a previous run of nebraska.py generates its pid/port files.

BUG=b:184980277
TEST=created a simple config.json file and did:
$ start nebraska
Then
$ cat /tmp/nebraska.log
INFO:root:Starting nebraska ...
