Operation to list installed Resource Adapters

Currently there's no way to list all the deployed Resource Adapters (modules or deployed archives). I propose to add a new operation to list installed RAs and their configuration, similar to the one available for JDBC drivers (see attached screenshots). This would allow HAL to provide a wizard of available options when configuring them.

The command would be something like: /subsystem=resource-adapters:installed-resource-adapters-list()
