Add content type name as a part of a new field name suggestion

Description of the need

When adding a new field to a content type, it automatically generates the field's machine name by using its title prefixed with field_:

In order to distinguish similar fields and to avoid mess in database, we always manually add the content type's name:

Proposed solution

I believe if the prefix consisted of field_ and content type's machine name like so field_listing_, it would only increase the usability and comfort of developing.
