cli,glusterd: Task parameters in xml output

This patch introduces task parameters for the asynchronus task shown in
volume status. The parameters are only given for xml output. The
parameters shown currently are,
- source and destination bricks for replace-brick tasks
  ......
        <tasks>
          <task>
            <type>Replace brick</type>
            <id>3d1a1005-9d2e-4ae0-bd62-577bc1d333a3</id>
            <status>1</status>
            <params>
              <srcBrick>archm:/export/test4</srcBrick>
              <dstBrick>archm:/export/test-replace1</dstBrick>
            </params>
          </task>
        </tasks>
  ......
- list of bricks being removed for remove-brick tasks
  ......
        <tasks>
          <task>
            <type>Remove brick</type>
            <id>901c20ca-0da2-41de-8669-5f0caca6b846</id>
            <status>1</status>
            <params>
              <brick>archm:/export/test2</brick>
              <brick>archm:/export/test3</brick>
            </params>
          </task>
        </tasks>
