Create script to add ssh keys to acquia

[patcon]

ssh keys can be added through the cloud API. Would be great to create a job with build parameters that added/updated keys on acquia, making it more accessible (since Acquia doesn't allow all devs to have access to acquia network (boooooo...)

This probably best fits as a rerun script right now. Perhaps could use data from inception's data_bag/users dir, which should really be stored with the project anyhow. Need to figure out how best to store it though... Maybe just keep jenkins-inception as a submodule in the project, and then have a rake task or script to copy the config.yml and data_bags/users into place...?
