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 Change-Id: Idb7891b3e056d46d570bb7e31bad1b6a28656ada Signed-off-by: Poornima G <pgurusid@redhat.com>
