"User Types" plugin, or perhaps extend base type plugin

On second thought, this seems like a variation of the existing base-type plugin, in that, in its default configuration, that plugin currently creates a package for each node bundle (content type). We could extend that to include user bundles.

Here is a patch implementing this.

It introduces a second set of checkboxes to the 'base-type' assignment plugin configuration form, for selecting entity types. Screenshot:

The patch also includes #2579763: Only list bundle-providing configuration types as options for 'base-type' assignment plugin. We limit the configuration types shown to those that provide bundles to other entity types. Then, when listing entity types, we show only those that are content bundle types and do not have their bundles provided by other entity types. This way, we don't end up with duplicated options. (For example, since the node_type (Content type) configuration entity type provides bundles (for node), it appears in the first list but node doesn't appear in the second.

By setting 'user' as a default content entity type, a new 'user' package is generated. While no configuration is added to it in this assignment plugin, it will get configuration assigned if other plugins like namespace are enabled.

A fair bit of this patch is just what's needed to inject the entity.manager service.

Note that this patch will break backward compatibility for plugin configuration, because it changes the format from

   types:
     node_type: node_type

to

   types:
     config:
       node_type: node_type
     content:
       user: user

Applied. As noted, this will break backwards compatibility.

Tips for fixing your site after updating.

• Clear caches.
• In your features Bundle configuration, open the configuration forms for each assignment plugin in turn and configure. If you want to match the default settings, configure as follows:
  • For "Exclude": ensure nothing is checked under "Configuration types" and click "Save settings".
  • For "Base type", select "Content type" under "Configuration types" and "User" under "Content entity types" and click "Save settings".
  • For "Core type", select "Field storag", "Role", "Text editor", and "Text format" under "Configuration types" and click "Save settings."

We're in alpha. Should there nonetheless be an update here? If you think so, please reopen this issue.
