    Let haproxy_defaults be overridable

    Add the haproxy_defaults_override parameter so the defaults_options
    in haproxy are overridable. Tested by adding the following yaml to
    the deployment:
    parameter_defaults:
      ExtraConfig:
        tripleo::haproxy::haproxy_defaults_override:
          retries: 7

    Observed that haproxy.conf contained the following (retries defaults
    to 3):
    defaults
      retries 7
