BREAKING CHANGE: use a specific xud-docker branch to launch

This commit enables the binary launcher to use a specific xud-docker
branch to setup the whole environment. It's related to
ExchangeUnion/xud-docker#836. It will download xud-docker launcher
binary file into ~/.xud-docker/launcher/versions/<commit> and delegate
all CLI commands to xud-docker launcher.
