Subject: quorum: Add quorum_open() and quorum_close().

Example of command line:

-drive if=virtio,driver=quorum,\
children.0.file.filename=1.raw,\
children.0.node-name=1.raw,\
children.0.driver=raw,\
children.1.file.filename=2.raw,\
children.1.node-name=2.raw,\
children.1.driver=raw,\
children.2.file.filename=3.raw,\
children.2.node-name=3.raw,\
children.2.driver=raw,\
vote-threshold=2

blkverify=on with vote-threshold=2 and two files can be passed to
emulate blkverify.
