> S3 head uses OM API lookup key which refreshes pipeline info by contacting
> SCM.
> For S3 head we donot require any pipeline info, we need very basic details
> like length, type, etag and last modification time.
> By removing pipeline info which is not required for HEAD object, HEAD API
> performance can be improved.
> This is identified during looking up graphs from [~kerneltime] testing
