HMS v3.0.0

In this release we changed the names of the server related commands to avoid clashes with client specific commands when autocompleting.

hms terminal is now hms run-terminal and hms dock is now hms run-dock. The arguments are the same.

Further more, we changed the format of specifying multiple environment variables when adding a remote. In the previous versions the system accepted a comma-seperated, this has been replaced with multiple --env arguments instead.

hms add remote service-name --env FOO=1 --env BAR=2
