stack_domain_admin_password = None	(StrOpt) Keystone password for stack_domain_admin user.
stack_scheduler_hints = False	(BoolOpt) When this feature is enabled, scheduler hints identifying the heat stack context of a server or volume resource are passed to the configured schedulers in nova and cinder, for creates done using heat resource types OS::Cinder::Volume, OS::Nova::Server, and AWS::EC2::Instance. heat_root_stack_id will be set to the id of the root stack of the resource, heat_stack_id will be set to the id of the resource's parent stack, heat_stack_name will be set to the name of the resource's parent stack, heat_path_in_stack will be set to a list of tuples, (stackresourcename, stackname) with list[0] being (None, rootstackname), heat_resource_name will be set to the resource's name, and heat_resource_uuid will be set to the resource's orchestration id.

multi_cloud = False	(BoolOpt) Allow orchestration of multiple clouds.
[eventlet_opts]
client_socket_timeout = 900	(IntOpt) Timeout for client connections' socket operations. If an incoming connection is idle for this number of seconds it will be closed. A value of '0' means wait forever.
wsgi_keep_alive = True	(BoolOpt) If False, closes the client socket connection explicitly.
[heat_api]
backlog = 4096	(IntOpt) Number of backlog requests to configure the socket with.

key_file = None	(StrOpt) Location of the SSL key file to use for enabling SSL mode.
max_header_line = 16384	(IntOpt) Maximum line size of message headers to be accepted. max_header_line may need to be increased when using large tokens (typically those generated by the Keystone v3 API with big service catalogs).
tcp_keepidle = 600	(IntOpt) The value for the socket option TCP_KEEPIDLE. This is the time in seconds that the connection must be idle before TCP starts sending keepalive probes.
