Allow checking out of different types of branches

Currently the branch created is in the format "feature/<JIRA Issue #>", however if the issue is not a feature (say a hotfix, etc) that isn't reflected in the branch name as it should be. Perhaps the type of release should be either defined in the RFC ticket or as part of the CLI checkout so that branch name reflects the type of change / release being created.

This makes sense; feature is not appropriate in all contexts. Ideally this would be managed in Jira; if it's type:Bug we call the branch bugfix/<Jira Issue #>?
