qmp: add test tool for QMP
Anthony wrote this quickly to aid in testing. It's similar to qmp-shell with a few important differences: 1) It is not interactive. That makes it useful for scripting. 2) qmp-shell: (QEMU) set_password protocol=vnc password=foo 3) qmp: $ qmp set_password --protocol=vnc --password=foo 4) Extensible, git-style interface. If an invalid command name is passed, it will try to exec qmp-$1. 5) It attempts to pretty print the JSON responses in a shell friendly format such that tools can work with the output. Hope others will also find it useful. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Mark Wu <wudxw@linux.vnet.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
