Support r10k's `authorization_token` setting for `bolt puppetfile install`

[caseywilliams]

Use Case

When downloading modules from a private artifactory puppet repository via r10k (and soon, when downloading certain new modules from the Forge), users sometimes need to specify an authorization_token setting in their r10k.yaml config file. It would be helpful to offer this same setting in bolt somehow, for when users run bolt puppetfile install etc. - here's the setting in the r10k docs.

Describe the Solution You Would Like

Open to other opinions, but I think it would be good if bolt offered an equivalent authorization_token setting somewhere and passed it directly through in the config when running r10k.
