Subject: [PATCH 459/493] glfsheal: add a '--nolog' flag
(Upstream master patch: https://review.gluster.org/#/c/glusterfs/+/21501/)
....and if set, change the log level to GF_LOG_NONE. This is useful for
monitoring applications which invoke the heal info set of commands once
every minute, leading to un-necessary glfsheal* logs in
/var/log/glusterfs/. For example, we can now run
`gluster volume heal <VOLNAME> info --nolog`
`gluster volume heal <VOLNAME> info split-brain --nolog` etc.
The default log level is still retained at GF_LOG_INFO.
The patch also changes glfsheal internally to accept '--xml' instead of 'xml'.
Note: The --nolog flag is *not* displayed in the help anywhere, for the
sake of consistency in how the other flags are not displayed anywhere in
the help.
