Dropped deprecated return values in floating_ip_info and assert remaining fields

Attributes such as location and tenant_id are computed by OpenStack
SDK. We do not return these fields in floating_ip_info because e.g.
tenant_id has been marked as deprecated and is a copy of the
project_id field.

Ref.: 70a06d9990

Added an assertion to CI which checks that all advertised fields
are returned by floating_ip_info. This helps with detecting breaking
changes in future updates.
