Registers certain driver actions that cannot be safely run concurrently in threads across multiple instances. Typically this might be used for create or destroy actions that use an underlying resource that cannot be used at the same time.
A shared mutex for this driver object will be used to synchronize all registered methods.
@example a single action method that cannot be run concurrently
no_parallel_for :create
@example multiple action methods that cannot be run concurrently
no_parallel_for :create, :destroy
@param methods [Array<Symbol>] one or more actions as symbols @raise [ClientError] if any method is not a valid action method name
