fix(clone): ssh connection may require user input (key unlocking etc)

Anything that requires user input (such as a key unlock or hostkey
verify) will block the terminal and wait for input which will never
come.

When cloning or configuring a repo via ssh we therefore initially
connect to gitlab to warm the connection.

Afterwards users are expected to either have setup a ssh ControlMaster
or use something like a ssh agent.

Fixes #148

Component: pkgctl repo clone/configure
