Add Config tree commands

[yaziine]

This PR adds commands to manage configuration:

• add a new configuration
• remove a configuration
• list all configuration
• set a default configuration

An app configuration is represented by:

• an API key
• an API secret key
• an URL (default to edge)
• a default boolean

The first new added configuration will be considered as the default one, this can be change with the default command.

How is deleting a default app config supposed to be working? Since we clear default, are we making config invalid at this stage or are we going to take first if default is missing since apps is a list, that makes sense to me.

Thanks for asking. Here is how I see it:

• if --app is provided it should work, eg:

  stream-cli channels create XYZ --app prod

• if --app is not provided it should fail with an error, eg:

  no default application configured, please use --app or define a default app using `stream-cli config default` command

Sounds good, explicit
