List state values command

[gitressa]

Is your feature request related to a problem? Please describe.

You can list the state values with this:

$ drush sql:query "SELECT name FROM key_value WHERE collection='state'";
comment.maintain_entity_statistics
comment.node_comment_statistics_scale
install_task
install_time
node.min_max_update_time
router.path_roots
[...]

From https://www.drupal.org/docs/8/api/state-api/overview#s-access-state-values-with-drush

Describe the solution you'd like

It would be nice to be able to list the current states with a Drush command instead, like this.

drush state:list

Or perhaps show a selectable list, like config:get does, when run without a parameter?

$ drush state:get
 Choose a configuration:
  [0] comment.maintain_entity_statistics
  [1] comment.node_comment_statistics_scale
  [...]
  [22] twig_extension_hash_prefix
  [23] update.last_check
  [24] update.last_email_notification
  [25] views.view_route_names
