Construct connection-specific resource names in Internal Kafka REST responses

[rohitsanj]

(Mentioned as a followup in #74)

The Internal Kafka REST API responses include "resource_name": null, whereas confluentinc/kafka-rest constructs a "Confluent Resource Name" of the format crn://<authority>/resource=name/sub-resource=name.

We need to construct CRNs based on the type of Confluent-flavored Kafka cluster (CCloud, CP, Confluent Local), as well as determine what the names should default to for non-Confluent flavored clusters.

To start, look for the TODO statement as follows:

// TODO: Construct resource name based on the connection/cluster type

stopping work here, no plans to use CRNs in the vscode extension as of this date
