    Add a new configuration option to define the default connection_limit for
    new listeners that use the Amphora provider. The option is
    [haproxy_amphora].default_connection_limit and its default value is 50,000.
    This value is used when creating or setting a listener with -1 as
    connection_limit parameter, or when unsetting connection_limit parameter.

    With haproxy 1.8.x releases, haproxy consumes much more memory in the
    amphorae because of pre-allocated data structures. This amount of memory
    depends on the maxconn parameters in its configuration file (which is
    related to the connection_limit parameter in the Octavia API).
    In the Amphora provider, the default connection_limit value -1 is
    now converted to a maxconn of 50,000. It was previously 1,000,000 but that
    value triggered some memory allocation issues when quickly performing
    multiple configuration updates in a load balancer.
