Additional logging during drupal:update command

[dan612]

Is your feature request related to a problem? Please describe.
When performing code deployments using BLT the drupal:update command is invoked. This command should update the database and import configuration. However, if the configuration management strategy is set to none in BLT.yml then this will simply return with a cache clear (https://github.com/acquia/blt/blob/main/src/Robo/Commands/Drupal/ConfigCommand.php#L60) prior to any additional information being output.

Describe the solution you'd like
Add some more logging within the conditional:

if ($strategy === 'none') 

something to let the user running the command know that in their BLT.yml file they have specified none - and this means no configuration import is going to take place.
