Disambiguating multiple resources of same type when binding applications

Currently the logic of binding is based on using the 'type' of the resource defined in an environment.

However, this approach will break if the environment definition contains two resources of the same type.

One approach to address this issue is to add a 'name' attribute for resource declaration in an environment definition. Each resource should have a unique name within an environment. Then when declaring environment variables we can use the name attribute in creating the bind parameters in application yaml
