Provide an option to configure fetchOwner when creating the minio client

[sjstyle]

• Description

I noticed that in api-list.go, line 71, the fetchOwner flag is hardcoded to true. This makes it impossible to create a request with fetchOwner set to false.

• Proposed Solution

It would be great to provide an option to configure the fetchOwner setting when initializing the minio client. This change would add flexibility for users who may not require the owner's information with every request.

• Additional Note

If the maintainers agree that this feature is necessary but are currently unable to address it, I would be happy to submit a PR for this improvement.
