KEP-2593 proposed to expand the existing node-ipam controller
to be configurable via a ClusterCIDR objects, however, there
were reasonable doubts on the SIG about the feature and after
several months of dicussions we decided to not move forward
with the KEP intree, hence, we are going to remove the existing
code, that is still in alpha.

A few notes about the change:
1. I need to initialize the fileclient once, in an init function, so I
don't have access to `testing.T` yet.
2. I want to be able to configure the openapi files that I use
3. We already have a "cache" client that wraps another client, we don't
need to re-implement caching here, one can just do:
`cache.NewClient(openapitest.NewFileClient("some/path"))` to do a cached
client. Or initialize it in an init/global var.
Since there is still some value to use the embedded file, make an
alternative constructor while using fs.FS interface to be able to
manipulate both virtual and disk-based filesystems.
