libglusterfs: Provide ability to filter output of state dump
Output of statedump can be controlled by having file /tmp/glusterdump.input.
/tmp/glusterdump.input needs to have a <key>=<value> in each line.
key can be one of 'priv', 'fd', 'inode', 'mem', 'callpool' and 'iobuf'.
value has to be one of 'yes' or 'no'.
If /tmp/glusterdump.input is not available, no filtering happens in statedump.
Else statedump would contain only those sections which correspond to a <key>
having value 'yes'.
