Wicket packaging

[andrewjstone]

Package up wicketd and wicket with omicron-package. I tested this out locally, and it seemed to work.

There are a couple things remaining to do:

• We need to be able to have the BOOTSTRAP_ARTIFACT_PORT listen on a bootstrap address. It's currently hardcoded to use localhost which is wrong.
• Should sled-agent construct a config file for wicket so it knows how to contact wicketd? Currently the wicketd port is just hardcoded inside wicket.

The first should probably be done in this PR. The second can likely wait until we figure out how we are going to launch wicket.

I had a brief chat in network channel with @rcgoodfellow, and he wasn't expecting to advertise bootstrap prefixes from the switch zone. He said it can be done, but the alternative is to move the artifact server into the sled-agent itself. We were going to do this anyway for recovery, so maybe having it in one place makes sense. More to be discussed tomorrow.

This has evolved into a larger discussion. For now, since the wicketd artifact server isn't actually in use yet, I suggest doing any networking or zone changes in a follow up PR, rather than cramming them in here.

Looks good, thanks!
