Change Details

- Created module structure for gRPC service handlers to keep it organized: ``` - mod service (existing grpc service mod) - mod handlers (groups all handler submodules) - create_backup - add_attachments - ... ``` - Scaffolded the `CreateBackupHandler` structure, containing the whole endpoint logic - Implemented usage of this structure in the endpoint handler function. The `CreateBackupHandler` consists of two phases 1. Non-data mode - processing non-chunk inputs like `device_id`, `user_id` etc. 2. Data mode - processing backup data chunks 3. Finish - postprocessing, saving to db etc. Depends on D6181

This is 1:1 analogy with Blob service `PutHandler` - Implemented usage of this structure in the endpoint handler function. The `CreateBackupHandler` consists of two phases 1. Non-data mode - processing non-chunk inputs like `device_id`, `user_id` etc. 2. Data mode - processing backup data chunks 3. Finish - postprocessing, saving to db etc. Depends on D6181
