feature/changelog: Virtual xattr to trigger explicit sync in geo-rep.
A virtual xattr "glusterfs.geo-rep.trigger-sync" is provided
in glusterfs through changelog translator. Geo-rep triggers
a explicit data sync on setting this xattr on a file.
Changelog captures a DATA entry on file's gfid on setting this
virtual xattr on a file. This is supported only for files. It
doesn't support directories.
Usage: setfattr -n glusterfs.geo-rep.trigger-sync <file-path>
