    Fix service subnet capacity within service_instance module

    Module 'service_instance' creates service_subnet per neutron_subnet,
    current mask is 29, that allows take only 3 (three) ips for service
    instances. Changed mask to 28, that allows take 11 (eleven) ips now
    by default.
    It allows us to use multibackend installation with drivers, that
    depend on this module more reliably and provides possibility to
    change this value in general.

    Changes:
    - added config option for network subnets mask with default value 28,
      instead of hardcoded 29.
    - fixed related unittests
