ported docker

Also, implemented modifyHostProps to add properties to an existing host.
Using it bypasses some type safety. Its use in docker is safe though.

But, in Conductor, the use of it was not really safe, because it was used
with a DebianLike property. Fixed that by making Ssh.installed
target all unix's, although it will fail on non-DebianLike ones.
