Resolve "Build an abstract client for output"

General MR

Summary

This MR introduces an abstract client for output handling in bbctl. The implementation follows a similar pattern factory pattern and prints to stdout. The output client is designed to support multiple output formats: human-readable,JSON, and YAML.

the client usage is fairly straight forward

• Create Client: Select one of 3 formats: "text", "json", "yaml" and include stream
• Use the Output method to write to stdout in the selected format

client := output.NewOutputClient(format,streams)  
err := client.Output(data)
