Subject: [PATCH] Change container_quota_items float columns to decimals

Fixes https://github.com/ManageIQ/manageiq-providers-kubernetes/issues/208
Kubernetes quotas are mostly integers but cpu-related quotas are
in "millicores", multiples of 0.001.
With decimal columns, we'll be able to round-trip quotas exactly to DB
and back to Ruby, so refresh can determine whether they changed or not.
