FilterScheduler is the only scheduler driver that properly integrated
with placement api so this patch changes the functional test environment
to use the FilterScheduler instead of the ChanceScheduler.
The amount of vcpu the SmallFakeDriver reports need to be bumped to 2
as during resize to same host the filter scheduler doubles the
allocation on the host. Simply relying on the 16.0 default allocation
ratio does not work as the max_unit of the vcpu does not use the
allocation ratio to avoid that a single server overallocates the cpu.
The only change in unit test is
test_create_instance_with_oversubscribed_cpu which also loads the
SmallFakeDriver and asserts available resources on it.

After this microversion Nova API the GET request to
/v2.1/os-hypervisors/{hypervisor_id} responses cpu_info
as regular JSON object instead of string.
