Run agent config tasks before post_install

The agent config tasks typically prep config directories and install
pip packages, so they should be run before the configs are dropped
or we run into issues dropping agent configs due to nonexisting
directories.

Aside: this also contains an update to the calico and dragonflow
test inventories, which currently always fail because the "openstack1"
container does not exist anymore as per
I672ceb0848415c8f2653ebc8f7556db77f7f001c.
