pytools: obmcutil: Add `chassiskill` command

Nick reported an issue where the BMC became unusable after the host hit
a bug and began "spewing a lot of messages to the console".  Save
ourselves some DBus transactions and immediate execution of systemd
transitions by introducing a `chassiskill` command to directly deassert
the the power-up GPIO ourselves.  This will immediately terminate the
host and free up resources for the BMC to become responsive. As a bonus,
the PGOOD monitoring will then execute to clean up the resulting
inconsistent BMC/Host state for us.
