DevStack: Calico bird cannot start

[YujiAzama]

In devstack,
c006bbdeb26df2c60f43d222bdf918f9e24d551f changed USE_SYSTEMD default.

auto-bird-conf.sh is not developed assuming USE_SYSTEMD.

The devstack log is shown below:

    DevStack plugin: fix for recent neutron and devstack changes

    - Set variables so that configure_neutron_after_post_config does not set
      service_plugins. (What changed here has that neutron-legacy's setting
      of service_plugins was deferred. Previously neutron-legacy set some
      value, and then the networking-calico deleted that. Now
      neutron-legacy sets its value after the last time that the
      networking-calico plugin code has run.)

    - Don't use systemd, as our running of auto-bird-conf is not
      systemd-compatible yet.

    - Remove 'coverage=eventlet' declaration from .coveragerc.

    - Also disable q-metering, as we have no use for it.
