Test for certificate error and prompt to regenerate

This resolves an issue where if the `${DOCKER_MACHINE_NAME}` VM was ever removed from `docker-machine` the build process would enter an infinite loop, with the following error being redirected to `/dev/null`.

>Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.102:2376": open /Users/weeks/.docker/machine/machines/kube-dev/server.pem: no such file or directory You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'. Be advised that this will trigger a Docker daemon restart which will stop running containers.

Now the output is tested for the error string and if found prompts the user if they want to regenerate the certificate. Another option would be setting the `--force` flag on `docker-machine regenerate-certs`, so user intervention wouldn't be required.
