    Tune up report and downtime intervals for l2 agent

    If the neutron server erroneously thinks that the l2 agent is down
    it will fail to bind a port, which can lead to VM's spawn errors.
    However, the issue is only transient because the agent effectively
    is only 'late' in reporting back.

    Best solution would be an alpha-count algorithm (so that we can detect
    persistent failures more reliably), but for now let's be more tolerant
    assuming that the agent is down by waiting at least twice the report
    interval plus a tiny teeny bit.

    (cherry picked from commit 291048aba2fcaec8afee3011fb4c12c6ca0ebbba)
