protocol install to launch a new application

[jonathonbyrdziak]

Need a new command like protocol install <git-repo-url>.

This would run through the installation steps as follows:

• protocol env:check - to make sure we have all the dependencies installed
• protocol key:generate - If we don't have git access - to create a key on the local server
• protocol git:clone - to clone down the repo - of course this needs to be fixed to install into the current dir
• protocol config:init - to initialize the config repo
• protocol start - to boot up the system
