            #     <operator> can be "<, >, <=, >=, !=, =, :". Of which ":" means HAS, and
            #     is roughly the same as "=".
            #     <value> must be the same data type as field.
            #     <logical connector> can be "AND, OR, NOT".
            #

            #     * "labels.owner" returns Namespaces that have a label with the key "owner"
            #       this is the same as "labels:owner".
            #     * "labels.protocol=gRPC" returns Namespaces that have key/value
            #       "protocol=gRPC".
            #     * "name>projects/my-project/locations/us-east/namespaces/namespace-c"
            #       returns Namespaces that have name that is alphabetically later than the
            #       string, so "namespace-e" will be returned but "namespace-a" will not be.
            #     * "labels.owner!=sd AND labels.foo=bar" returns Namespaces that have
            #       "owner" in label key but value is not "sd" AND have key/value foo=bar.
            #     * "doesnotexist.foo=bar" returns an empty list. Note that Namespace doesn't
            #       have a field called "doesnotexist". Since the filter does not match any
            #       Namespaces, it returns no results.

            #     Optional. The order to list result by.
            #

            #     <field> can be "name", or "metadata.<key>" for map field.

            #     is roughly the same as "=".
            #     <value> must be the same data type as field.
            #     <logical connector> can be "AND, OR, NOT".
            #

            #     * "metadata.owner" returns Services that have a label with the key "owner"
            #       this is the same as "metadata:owner".
            #     * "metadata.protocol=gRPC" returns Services that have key/value
            #       "protocol=gRPC".
            #     * "name>projects/my-project/locations/us-east/namespaces/my-namespace/services/service-c"
            #       returns Services that have name that is alphabetically later than the
            #       string, so "service-e" will be returned but "service-a" will not be.
            #     * "metadata.owner!=sd AND metadata.foo=bar" returns Services that have
            #       "owner" in label key but value is not "sd" AND have key/value foo=bar.
            #     * "doesnotexist.foo=bar" returns an empty list. Note that Service doesn't
            #       have a field called "doesnotexist". Since the filter does not match any
            #       Services, it returns no results.

            #     <value> must be the same data type as field.
            #     <logical connector> can be "AND, OR, NOT".
            #

            #     * "address=192.108.1.105" returns Endpoints that have this address.
            #     * "port>8080" returns Endpoints that have port number larger than 8080.
            #     * "name>projects/my-project/locations/us-east/namespaces/my-namespace/services/my-service/endpoints/endpoint-c"
            #       returns Endpoints that have name that is alphabetically later than the
            #       string, so "endpoint-e" will be returned but "endpoint-a" will not be.
            #     * "metadata.owner!=sd AND metadata.foo=bar" returns Endpoints that have
            #       "owner" in label key but value is not "sd" AND have key/value foo=bar.
            #     * "doesnotexist.foo=bar" returns an empty list. Note that Endpoint doesn't
