UndertowJSRWebSocketDeploymentProcessor uses hard coded IO module dependencies

UndertowJSRWebSocketDeploymentProcessor uses hard coded dependencies to a buffer pool und worker pool named "default" of the IO module.

My suggestion is to introduce two additional attributes "worker" and "buffer-pool" to the undertow module get rid of the hard coded pools. The default values will garanty a compatibility.

If you agree to this approach i'll provide a patch adding und using these attributes.
