Inefficient read of the entire resource tree in messaging subsystem socket binding analysis

The isOutBoundSocketBinding utility method is performing a read of the entire model. Worse, it gets called inside a loop.

Just non-recursively read the s-b-g names, and then non-recursively read each s-b-g (in reality there will only be one) to find the children.

For bonus points, pass in the entire list of a names and return a LinkedHashMap<String, Boolean> and process everything with one pair of reads instead of repeating for each name.
