nfs4-client: show layout types supported by the server

Motivation:
Current client uses LAYOUT4_NFSV4_1_FILES layout types independent from
what server is offering.

Modification:
Update client to show server side supported layout types and disable pNFS
if client doesn't supports any of them.

Result:
more debug possibilities
