Command - refactor to use typed interfaces to implement commands for secure channel and secure channel listener

[nazmulidris]

Following the refactoring of RPC calls, we can now implement all commands using typed interfaces and implemented with a specific RPC client.

For example the Projects trait provides an access to projects, to create/list/delete them. That trait is implemented by the Controller client by making requests to the controller.

The use of the Projects interface can be seen in the following command to create projects.

Desired behavior

Provide similar interfaces for all other commands and remove all the "api helpers" from the ockam_command crate for the following:

• secure channel
• secure channel listener

All the interfaces and implementations must be part of the ockam_api crate so that the purpose of the ockam_command is only to:

• get and validate arguments from the command line
• call the ockam_api crate
• display progress / reports / outputs / errors
