stream: set connection monitor delay. (#1120)

- this fixes a bug where the connection monitor delay config value does not
get set to the websocket on intialization.

- this adds the connection monitor delay config option to the exchange type.
- the validate function of the exchange type has been updated to validate the
connection monitor delay value as well.
