Should BucketExists (HeadBucket) fail because of an error related to
the connection rather than the existence of the bucket, no information
is available and the admin is left guessing.

GetBucketVersioning is used instead and exclusively dedicated to
asserting if using the connection does not return a BadRequest.
If it does the NewMinioStorage logs an error and returns. Otherwise
it keeps going knowing that BucketExists is not going to fail for
reasons unrelated to the existence of the bucket and the permissions
to access it.
