Githooks requires use of node where you run git commands

[grayside]

In some workflows git is run in one environment, but operational dependencies may be silo'd into a separate virtual or containerized environment. The new (in 0.9) githooks functionality makes grunt-drupal-tasks a dependency of git.

A workaround for this problem might go as follows:

• Add a Gruntconfig option to suppress the git-setup warning. Currently you must have a pre-commit hook or suppress validate errors to negate this warning.
• Adjust the githook task configuration to allow setting the command option, which would allow us to swap out the assumption that grunt is the base command with something else, e.g., docker exec <container> grunt.
