Title:
  Sanity checks comparing versions should not use decimal comparison

Status in neutron:
  Fix Released

Bug description:
  In sanity check "dnsmasq_version_supported", the binary version is checked comparing the version number converted to float. This can lead to errors like the following one:
    version = 2.9
    min_version_required = 2.76

    version < min_version_required ==> False, but v2.9 is older than
  v2.76

  Here we need to use the oslo utils method "convert_version_to_tuple",
  and then compare the version tuples.
