If quorum's child is broken, we can use mirror job to replace it.
But sometimes, the user only need to remove the broken child, and
add it later when the problem is fixed.
It is based on the Kevin's child name related patch:

ChangLog:
v8:

2. Address the comments from Eric Blake
v7:
1. Remove the qmp command x-blockdev-change's parameter operation according
to Kevin's comments.
2. Remove the hmp command.
v6:
1. Use a single qmp command x-blockdev-change to replace x-blockdev-child-add
and x-blockdev-child-delete
v5:
1. Address Eric Blake's comments
v4:
1. drop nbd driver's implementation. We can use human-monitor-command
to do it.
2. Rename the command name.
v3:
1. Don't open BDS in bdrv_add_child(). Use the existing BDS which is
created by the QMP command blockdev-add.
2. The driver NBD can support filename, path, host:port now.
v2:
1. Use bdrv_get_device_or_node_name() instead of new function
bdrv_get_id_or_node_name()
2. Update the error message
3. Update the documents in block-core.json
Wen Congyang (3):
Add new block driver interface to add/delete a BDS's child
quorum: implement bdrv_add_child() and bdrv_del_child()
qmp: add monitor command to add/remove a child
