Add an unencrypted file based backend.
Split out djset classes into a base, config, and secrets. Split commands into two: djsecret and djconfig. Change the namespace to remove the key prefix (there are other potential ways to distinguish the key value pairs manually in the backend, and keeping project key pairs under the same keyring service makes better sense.). Allow a prompt_help option on get and also make keyring and error handling when no value returned configurable.
Can now import an initialized object for DjSecret and DjConfig
