cli: Add options to the CLI that let the user control the reset of
stats "volume profile info" automatically clears incremental stats. There isn't a command to: - fetch stats without clearing incremental stats and - clear cumulative and incremental stats This change introduces two arguments (i.e. peek and clear). 'clear' will wipe both incremental and cumulative stats. 'peek' fetches stats without wiping incremental stats. 'volume profile info peek' - fetches incremental and cumulative stats without wiping incremental stats 'volume profile info incremental peek' - fetches incremental stats without wiping incremental stats 'volume profile info clear' - clears both incremental and cumultiave stats Change-Id: I91834515ad672eca5f882809941147d7d997c4c9 BUG: 1047416 Signed-off-by: Dawit Alemu <dalemu@redhat.com> Reviewed-on: http://review.gluster.org/6620 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaushal M <kaushal@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
