dockererized rhizi

[alon]

update rhizi-mux to have docker functionality.

rz-mux docker list

• shows the rhizi dockers

rz-mux docker create

• checks for existence of /
• checks for existence of expected files
• creates the docker instance containing a neo4j and rhizi server instance
• copies the customization code
• sets the docker instance to start on boot of the computer
• starts the docker instance
• verifies it is alive (use the same monitoring code)

nicer:

• automatically upgrade to latest version of customization code
• (related) allow providing a git url for customization, and then pull that periodically
• (related) or accept a push
• integrate into monitoring - add this new site to be monitored
• integrate into backup - add this new site to backups

possibly consider kubernetes instead of direct docker.
