Miscellaneous Fixes to Augur New

[ABrain7710]

Description

1. Changed the cli options for augur config init to use dashes in the option names rather than underscores
2. Added a logger to the RandomKeyAuth class, so it can log when there are no valid keys. Before it was erroring because someone tried to log this statement using self.error()
3. Fixes the regex expressions in the repo load controller to allow for .github and .github.io repos

This PR fixes

1. Error when deleting users. The API to delete a user now deletes all the users repos in the user_repos table before deleting the user from the users table.
2. Fixed the user/update API. Now it returns missing argument if either user or password is None, rather than only when user is None. It also checks to make sure an email or username isn't already taken when updating them. It also returns missing argument now if only the username and password are returned. Lastly, I removed an unneeded else since the API returned inside of the if clause.
