Document compile command on bosh.io

[jpalermo]

https://github.com/cloudfoundry/bosh-agent/pull/315 added the compile command, but we don't have docs that explain how it can be used.

Would this document be a good spot to PR some documentation?

Can the stemcell container images pull-able from outside the corporate network? Can a open source user build an image?

The easiest-to-follow documentation would be container (Docker) based. I don’t think documenting how to do a compilation from a BOSH Deployed VM is particularly useful since in that case you might as well use a deployment.

taking a warden stemcell, untarring it, and running a docker import on the image file should work. But I agree ideally we publish stemcell images to an OCI image registry.

The warden stemcell thing sounds like a fun thing to learn anyways. I'll time box figuring that out and documenting it.
