Add ODL variables to env file

ODL testcases in functest require new variables:

https://git.opnfv.org/functest/tree/functest/utils/env.py#n22

Otherwise the test fails because it cannot contact ODL

To find those variables, we fetch the ml2_conf.ini file from the neutron
container and then we parse the values. This is only run when the
scenario has odl

deploy-scenario:os-odl-sfc
installer-type:osa
