AWS SDK operations in Ethereum account "Delete" and "Destroy" are inappropriate

[amane-c]

Describe the bug

In the case of using AWS KMS,

Delete Ethereum Account is not implemented as soft deletion, but schedule hard deletion.
https://consensys.github.io/quorum-key-manager/#tag/Ethereum/paths/~1stores~1%7BstoreName%7D~1ethereum~1%7Baddress%7D/delete

Destroy Ethereum Account ignores hard deletion and only removes the entry in the database.
https://consensys.github.io/quorum-key-manager/#tag/Ethereum/paths/~1stores~1%7BstoreName%7D~1ethereum~1%7Baddress%7D~1destroy/delete

Configuration

We are using main(d509f52) version of QKM and AWS KMS configuration.

Steps to reproduce

1. Execute "Delete Ethereum Account"
2. Check AWS CloudTrail

Actual result

To find ScheduleKeyDeletion

Expected result

To find DisableKey

Additional context

In the following part, soft deletion("DeleteKey()") uses "ScheduleKeyDeletion".
https://github.com/ConsenSys/quorum-key-manager/blob/d509f52d9ab3d6476327415a6d276f4e570b50e2/src/infra/aws/client/kms.go#L143

But, ScheduleKeyDeletion is a destructive operation, not soft deletion. "DeleteKey()" should use "DisableKey".
https://docs.aws.amazon.com/kms/latest/APIReference/API_ScheduleKeyDeletion.html

In addition, "Destroy()" should be implemented as the current implementation of "Delete()".
The following part ignores the deletion operation.
