Test suite support for QEMU boot features

QEMU does not have a host nor can it reboot.  There are test cases
that force the BMC to reboot and others that issue power on
commands.  I am implementing two tags that descrbie what the
test will need to do.  The "bmcreboot" and "chassisboot" tags
will be used to skip tests that issue bmc reboots and chassis
boots.
