diag-mode: support entry into diagnostic mode

See DiagnosticMode definition in phosphor-dbus-interfaces for more
information:
https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/xyz/openbmc_project/State/Host.interface.yaml

This target will be started by other software entities within OpenBMC so
phosphor-host-state-manager will monitor for this target to start and
update its state accordingly. System defined behavior will then
transition the system out of this state (quiesce, off, warm-reboot) and
state-manager will update as needed when those are seen.
