tedge connect c8y should display the auth method used (certificates or basic auth) #3380
Description
Is your feature improvement request related to a problem? Please describe.
When using tedge connect c8y and setting the c8y.auth_method to basic, the command output displays incorrect information about the certificate.
Below shows an example of the output when using a username/password MQTT connection to Cumulocity.
$ sudo tedge connect c8y

Describe the solution you'd like
The tedge connect c8y commands (including the --test option), should display
- Show the certificate path only if a certificate is being used (note
c8y.auth_methodcan be set to eitherbasicorauto(wherebasicauth is used only if the given path (c8y.credentials_path) exists)
When using a certificate
$ sudo tedge connect c8y --test
