Version 1.0.0-beta.1 - API Update, Mocking and Unittests

[1.0.0-beta.1] - 2024-04-11

Added

• An interface for Fidelius gateway repos and admins to fulfil
• A mock implementation of a Fidelius gateway repo and admin that use a
  simple singleton dict to store (and share) data during runtime
• Unittests for the mock implementation
• Unittests for the Parameter Store implementation using LocalStack
• A Factory class to get different implementation classes
• Methods to delete parameters
• Config params for the AwsParamStoreRepo to use a custom AWS endpoint in
  order to hook up to stuff like LocalStack for testing and such

Changed

• The API a little bit so we're no longer backwards compatible (hence the
  major version bump to 1.0.0)
• All config params can now be explicitly given to the AwsParamStoreRepo
  in addition to being picked up from environment variables if not supplied
