Adding GitLab Runner Registration Token

[evanstucker-hates-2fa]

Example output for good token:

$ ./keyhacks.sh gitlab_runner_registration_token GR1348941RLoRqn-LN-ZsZHUoa23A
docker run --rm gitlab/gitlab-runner register --non-interactive --executor "docker" --docker-image alpine:latest --url "https://gitlab.com/" --registration-token "GR1348941RLoRqn-LN-ZsZHUoa23A" --description "keyhacks-test" --maintenance-note "Testing token with keyhacks" --tag-list "docker,aws" --run-untagged="true" --locked="false" --access-level="not_protected"

Runtime platform                                    arch=amd64 os=linux pid=7 revision=32fc1585 version=15.2.1
Running in system-mode.                            
                                                   
Registering runner... succeeded                     runner=GR1348941RLoRqn-L
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
 
Configuration (with the authentication token) was saved in "/etc/gitlab-runner/config.toml"

Example output for bad token (I just deleted the runner and reset the token):

$ ./keyhacks.sh gitlab_runner_registration_token GR1348941RLoRqn-LN-ZsZHUoa23A
docker run --rm gitlab/gitlab-runner register --non-interactive --executor "docker" --docker-image alpine:latest --url "https://gitlab.com/" --registration-token "GR1348941RLoRqn-LN-ZsZHUoa23A" --description "keyhacks-test" --maintenance-note "Testing token with keyhacks" --tag-list "docker,aws" --run-untagged="true" --locked="false" --access-level="not_protected"

Running in system-mode.
