    [OVS][FW] Initialize ConjIdMap._max_id depending on the current OFs

    The OVS Firewall has a singleton class that manages the conjuction IDs
    to used in the OF rules. Those conjuntions are used to group rules
    related to remote security group IDs.

    Now each time the OVS agent is started, the OVS Firewall initial
    conjunction ID is calculated based on the present OF rules. This value
    and the next one used won't clash with any present rule in the
    integration bridge during the initial transient period.
