Sanity E2E Test for OLT/ONU on POD With Core Fail and Restart for DT
    [Documentation]    Deploys an device instance and waits for it to authenticate. After
    ...    authentication is successful the rw-core deployment is scaled to 0 instances to
    ...    simulate a POD crash. The test then scales the rw-core back to a single instance
    ...    and configures ONOS for access. The test succeeds if the device is able to
    ...    complete the DHCP sequence.
