Allow uniform access rules on upload

[mattfoster7]

Currently the code forces an ACL on the files, this doesn't work if the bucket has uniform access policies set. So this PR just checks whether the bucket has uniform access before setting the ACL.

[mattfoster7]

The tests are failing because they are not scoped to work with this use case.

thanks @mattfoster7 for sharing this.
however , and until merging this I used your solution as a work around using Anonymous classes in PHP7

return new class ($storageClient, $bucket) extends GoogleStorageAdapter {
    protected function getOptionsFromConfig(\League\Flysystem\Config $config)
    {
        $options = [];

        if (empty($this->bucket->info()['iamConfiguration']['uniformBucketLevelAccess']['enabled'])) {
            if ($visibility = $config->get('visibility')) {
                $options['predefinedAcl'] = $this->getPredefinedAclForVisibility($visibility);
            } else {
                $options['predefinedAcl'] = $this->getPredefinedAclForVisibility(AdapterInterface::VISIBILITY_PRIVATE);
            }
        }

        if ($metadata = $config->get('metadata')) {
            $options['metadata'] = $metadata;
        }

        return $options;
    }
};

Shouldn't the visibility config be optional?
Instead of defaulting to private?

This way user can omit the configuration if they don't want to use the predefinedAcl option.
