Fix automatic subnet CIDR generation
This helps generating subnet masks by checking for
subnet masks already used from the same test class.
This also avoids having to check if a subnet with
conflicting subnet CIDR already exists treating
subnet error creation by looking in a local set
of already reserved CIDRs.
It fixes a problem that makes create_subnet
try to reuse the same CIDRs more than once
producing test failures.
It also allows methods to blank list some CIDRs
to avoid create_subnet from using it an therefore
avoid interferences.
