libglusterfs: Add put fop

Problem: It had been a longtime request to implement put fop
in gluster. put fop in gluster may not have the exact sementics
of HTTP PUT, but can be easily extended to do so. The subsequent
patches, will contain more semantics on the put fop and its
guarentees.

Why compound fop framework is not used for put?
Compound fop framework currently doesn't allow compounding of
entry fop and inode fops, i.e. fops on multiple inodes cannot be
combined in compound fop.

Updates #353
