            #     <field> can be "name", or "labels.<key>" for map field.
            #     <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".
            #
            #     Examples of valid filters:
            #     * "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.
            #   @param order_by [String]
            #     Optional. The order to list result by.
            #

            #     <field> allows values \\{"name"}
            #     <asc/desc> ascending or descending order by <field>. If this is left
            #     blank, "asc" is used.

            #     <logical connector> can be "AND, OR, NOT".

            #     * "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

            #     <value> must be the same data type as field.
            #     <logical connector> can be "AND, OR, NOT".
            #
            #     Examples of valid filters:
            #     * "metadata.owner" returns Endpoints that have a label with the key "owner"
            #       this is the same as "metadata:owner".

            #       "protocol=gRPC".
            #     * "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

            #
            # This class represents the configuration for RegistrationService,
            # providing control over timeouts, retry behavior, logging, transport
            # parameters, and other low-level controls. Certain parameters can also be
            # applied individually to specific RPCs. See
            # {Google::Cloud::ServiceDirectory::V1beta1::RegistrationService::Client::Configuration::Rpcs}
            # for a list of RPCs that can be configured independently.
            #
            # Configuration can be applied globally to all clients, or to a single client
            # on construction.
            #
            # # Examples
            #
            # To modify the global config, setting the timeout for create_namespace
            # to 20 seconds, and all remaining timeouts to 10 seconds:
            #
            #     Google::Cloud::ServiceDirectory::V1beta1::RegistrationService::Client.configure do |config|
            #       config.timeout = 10_000
            #       config.rpcs.create_namespace.timeout = 20_000
            #     end
            #
            # To apply the above configuration only to a new client:
            #
            #     client = Google::Cloud::ServiceDirectory::V1beta1::RegistrationService::Client.new do |config|
            #       config.timeout = 10_000
