distbuild: Add distbuild start and cancel functionality

Add command for distbuild-start to build_plugin in morphlib,
and create a boolean parameter to inform the initiator whether
to disconnect the controller and leave the build running remotely.

Add distbuild-cancel command to parse currently-running distbuild
build-request IDs and cancel the one matching the given argument
