fatal exit if branch is missing. can this be a warn and continue?

[elliot-tucker]

We generate the list of branches to track by reading consul keys and generating the git2consul config using consul-template, the idea being that we can dynamically generate the branch list from our CI/CD. If for any reason the branch is missing, git2consul will exit. Would be good to have the option to have this as a warn and continue and not a fatal.

(repo name: ourrepo, branch name: non-such).
