[FAB-8627] Add clientChannel timeout conf

	timeout logic for the client handler is:
	1. get timeout from options
	2. if empty, then get timeout from config
	3. if empty, then use default timeout set in 'defaultHandlerTimeout'

	Also exposed Timeout function in the config interface
	The client can now use either TimeoutOrDefault (with preset default
	if type is not found in the config) or call Timeout (default is 0 if
	type is not found)
