Low priority / not gating - no system impact; fix would help with debugging issues as the logs won't be lost, but influxdb is not a key component in starlingx and will be removed in stx.3.0.

    fix influxdb log file cannot be collected by logrotate

    The logfile for influxdb is influxd.log, not influxdb.log
    Correct the name in controller.yaml, so that logrotate could get
    the log correctly.
    Also, influxdb process uses error re-direction to append the error
    message to influxd.log, so "copytruncate" need be added in logrotate
    setting, so that log could be continue logged after logrotate
    execution.
