Separate admin test from RoutersNegativeTest
Most tests of RoutersNegativeTest don't require admin credential,
test_router_set_gateway_used_ip_returns_409 only requires it.
So this patch makes RoutersNegativeTest inherit from BaseNetworkTest
which is based on non-admin credential. In addition, this patch makes
a test stop using _add_router_interface_with_subnet_id() on the test
class for simple code and removing the dependency to BaseRouterTest.
NOTE: test_router_set_gateway_used_ip_returns_409 is not used on
defcore side. So this path change doesn't affect on defcore.
