protocol/client: add an option to filter O_DIRECT flag in open
with the option, the idea is all client-side caching will be disabled,
where as on server side process, the fd will be treated as a regular
fd, thus helping the performance better.
"gluster volume set <VOLNAME> remote-dio enable" would set
this option in client protocol volumes.
