OVN: bump the ovn-remote-probe-interval for ovn-controller

[Kamil Sambor]

For some deployments the default ovn-remove-probe-interval of 5000ms (5s) [0] is not enough.

If the ovn-controller takes more time recomputing the flows than the probe interval, chances are that it will try to reconnected to the SB OVSDB causing a full re-sync of the DB with it's in-memory replica (costy).

In order to change this default one can run the following command where the ovn-controller is running:

$ ovs-vsctl set open . external_ids:ovn-remote-probe-interval=<TIME IN MS>

We need to make it either configurable via Tripleo-Heat-Templates.

Perhaps even thing about a "saner" default to accommodate for bigger deployments which requires ovn-controller to process a lot of flows (e.g having a lot of SG and SG rules would result in a lot of flows being created for ACLs, specially in OSP 13 where we do not have Port Groups).

    Add the ability to configure ovn-remote-probe-interval

    This parameter sets inactive probe interval of the JSON
    session from ovn-controller to the OVN SB database.
    By default this it is 5s which not be sufficient in
    loaded systems or during high control-plane activity spikes,
    leading to unnecessary reconnections to OVSDB server.
    Now it is extended by default to 1 min and it
    is configurable.
