cli: Add statusStr xml tag to task list and rebalance/remove brick status

New xml tag statusStr added to following gluster cli commands
gluster volume status all --xml (For Task status)
gluster volume rebalance <VOLNAME> status --xml
gluster volume remove-brick <VOLNAME> <BRICK1..> status --xml

Example(volume status all):
<task>
    <type>Rebalance</type>
    <id>82d8d122-8738-4144-8507-d93fc98b61df</id>
    <status>3</status>
    <statusStr>completed</statusStr>
</task>

Example(volume rebalance <VOL> status)
<node>
    <nodeName>localhost</nodeName>
    <files>0</files>
    <size>0</size>
    <lookups>0</lookups>
    <failures>0</failures>
    <status>3</status>
    <statusStr>completed</statusStr>
</node>

Also modified task status as string instead of showing number
in gluster volume status all

Example:
Status of volume: gv1
