Description of problem:
OVN provider driver removal action does not remove all changes done by the installation and OVN configuration actions.

1. Python compiled file exists in:
/usr/lib/python2.7/site-packages/vdsm/tool/ovn_config.pyc
This is also relevant to (but not yet tested):
/usr/libexec/vdsm/hooks/before_device_create/ovirt_provider_ovn_hook.pyc
/usr/libexec/vdsm/hooks/before_nic_hotplug/ovirt_provider_ovn_hook.pyc

2. OVN bridge interface is not removed (created by setup_ovn_controller.sh):
ovs-vsctl show output:
    Bridge br-int
        fail_mode: secure
        Port br-int
            Interface br-int
                type: internal
        Port "ovn-9abf38-0"
            Interface "ovn-9abf38-0"
                type: geneve
                options: {csum="true", key=flow, remote_ip="10.35.128.5"}
    ovs_version: "2.6.90"

Version-Release number of selected component (if applicable):
ovirt-provider-ovn-driver: 1.0-1.fc24

How reproducible:
100%

Steps to Reproduce:
1. Install ovirt-provider-ovn-driver RPM on OVN node.
2. Use vdsm-tool ovn-config {provider_ip} {host_ip} to configure OVN tunnel.
3. Remove ovirt-provider-ovn-driver RPM from OVN node.

Actual results:
There are leftovers.

Expected results:
1. .pyc files should be removed from the installation directories.
2. Bridge interface should be removed.
