refactoring of transaction processing for storage

[kakcy]

RunTransaction, Begin, etc. are called and transaction processing is performed at the API layer.

Example of code that is an issue

• RunTransaction
  • https://github.com/bucketeer-io/bucketeer/blob/main/pkg/account/api/account.go#L64
• Begin
  • https://github.com/bucketeer-io/bucketeer/blob/main/pkg/autoops/api/api.go#L185

Solution

• Define the necessary API for each storage layer using Interface and abstract the storage layer.
  • In the storage layer, embed the interface for each storage and move the implementation necessary for DB operations to the storage layer.
  • The API layer calls the above Interface and does not directly perform DB operations.
• If transaction processing is required in the API layer, use RunTransactionAPI provided in the DB client to perform transaction processing.
  • If we want your API layer to handle transactions across different storages, we can do so by creating storage instances using the same DB client instance.
