Use standard Objects class instead of Guava

[Emkas]

Minimal Java version for the project seems to be 8 (source\targetCompatibility = JavaVersion.VERSION_1_8). There's no need to use Guava for equals and hashCode methods. I've changed com.google.common.base.Objects to java.util.Objects and this reduced number of imports from Guava by half.

All equals and hashcode looks automatically generated... So I'd be nice to ensure com.google.common.base.Objects woudn't be use in future, but I don't know how to achieve (I don't think that in Spotless we can achieve that). Assuming my pull request will be approved, of course :-)

Even though, it is not possible to completely get rid of Guava, the PR looks good to me. Methods hashCode() and equals() were actually written manually. This means it is possible to use import com.google.common.base.Objects; in future. Can you add a check in Github Workflow if com.google.common.base.Objects is used?

I have zero idea what Github Workflow is (yet :-)), but I'll try.

Just add grep check here https://github.com/minio/minio-java/blob/master/.github/workflows/gradle.yml#L23

@balamurugana Tell me if this is what you wanted. I had to 'negate' grep returning code, so I've made simple if based on https://github.com/actions/checkout/blob/main/.github/workflows/check-dist.yml#L40

Edit: OK, I forgot about ! operator. Now this is a one-liner.

Does this reduce the SDK size in some way?

Guava is still in use, so not really.
