cli : new volume statedump command
Changes: 1. Add a new 'volume statedump' command, that performs statedumps of all the bricks in the volume and saves them in a specified location. 2. Add new server option 'server.statedump-path'. 3. Remove multiple function definitions in glusterd.h Statedump Information: The 'volume statedump' command performs statedumps on all the bricks in a given volume. The syntax of the command is, gluster volume statedump <VOLNAME> [type]...... Types include, * all * mem * iobuf * callpool * priv * fd * inode Defaults to 'all' when no type is specified. The statedump files are created by default in /tmp directory of the server on which the bricks are present. This path can be changed by setting the 'server.statedump-path' option. The statedump files will be named as, <brick-name>.<pid of brick process>.dump Change-Id: I01c0e1a8aad490da818e086d89f292bd2ed06fd4 BUG: 1964 Reviewed-on: http://review.gluster.com/321 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com>
