Recent versions of Red Hat OpenStack Director's stable/mitaka release -- as of neutron 8.3.0-9 -- include a patch that was abandoned upstream (see stable/mitaka version of patch with the Change ID of Ie29acfbe323b60205ade9d660f7497f5bf4a35ca). While this patch addresses a bug found in some configurations, it removes code used by a similar monkey-patch applied in the GBP plugin. Since the abandoned patch provides the same protection as the GBP monkey-patch, we should only apply the GBP monkey-patch if the one from Red Hat hasn't been applied already.

Group Based Policy (GBP) provides declarative abstractions for achieving scalable intent-based infrastructure automation.
GBP complements the OpenStack networking model with the notion of policies that can be applied between groups of network endpoints. As users look beyond basic connectivity, richer network services with diverse implementations and network properties are naturally expressed as policies. Examples include service chaining, QoS, path properties, access control, etc.
GBP allows application administrators to express their networking requirements using a Group and a Policy Rules-Set abstraction. The specifics of policy rendering are left to the underlying pluggable policy driver.
GBP model also supports a redirect operation that makes it easy to abstract and consume complex network service chains and graphs.
