Integrate internal dev tools

[ripienaar]

Proposed change

We have 2 tools developed while supporting users that we'd like to include in the cli

• https://github.com/nats-io/nats.go/blob/stream-check/examples/consumer-check/main.go
• https://github.com/nats-io/nats.go/blob/stream-check/examples/stream-check/main.go

Requires some thought but would be great to figure out how to best to include them

Use case

Improve supportability
