What is the current behavior?
Aliases for acceptance tests only allow you to run the cucumber tests and run linting with no parameters.

What is the expected/proposed behavior?
Adding a bundlelock alias would allow the gemfile.lock to be updated within the container including passing in parameters to update individual gems.
The acclint alias could also pass through any parameters to allow auto-fixing of linting errors.

What is the motivation / use case for changing the behavior?
Simplicity and consistency.
