[1.0.0-rc.5] Last planned pre-release for 1.0.0

This adds all the changes since ArunaAPI version 1.0.0-rc.1.

Changes 1.0.0-rc.1:

• Added dummy implementation of paths logic for objects as prerequisite for the upcoming S3 compatibility
• Convert origin_id to a mandatory field for an object

Changes 1.0.0-rc.2:

• Implementation of paths logic for objects as prerequisite for the upcoming S3 compatibility
• Implemented tests for all the object path functionality
• Hash can be added now to an object on creation with the InitializeNewObjectRequest
• Removed the type from the origin part of a returned object as it poses no added value for the user

Changes 1.0.0-rc.4:

• Limit project/collection names to RFC3986 unreserved characters for path compliance
• Rollback useless migration which allowed objects to have two references (one static and one auto updating) parallel in a collection
• Restrict creation of object references:
  • Staging objects cannot be referenced in other collections anymore
  • References with auto_update == true can only be created for the latest revision of an object
• ObjectGroups can be deleted completely with the new with_revisions parameter of the DeleteObjectGroupRequest
• Refactor get_object and get_object_by_id functions to respect permission boundaries on object fetching

Changes 1.0.0-rc.5:

• Updated various dependencies to their latest version and fixed the breaking changes
• Added dummy implementation for the new InternalProxyNotifierService
