Entity annotation classes need more info in docs

Yes, that's what we're looking for!

A couple of things to fix:

a) Documentation lines should never go over 80 characters, so the new docs added to the two Annotation classes need to have their lines rewrapped.

b) I do not think the interface is correct in the Config annotation:

+ * \Drupal\Core\Config\Entity\ConfigEntityType and are accessed using get/set methods defined
+ * in \Drupal\Core\Config\Entity\ConfigEntityInterface.

ConfigEntityInterface is the interface for config entities, not config entity types (which apparently do not have their own interface -- they just use \Drupal\Core\Entity\EntityTypeInterface for their get/set methods).

Thanks!

Oh, I just noticed one more thing: The Annotation classes have @see to themselves:

 * @see \Drupal\Core\Entity\Annotation\ConfigEntityType
+ *
+ * @ingroup entity_api
+ *
  * @Annotation
  */
 class ConfigEntityType extends EntityType {

Same for Content one. Those can be taken out.

Oh, I see that was taken from the EntityType annotation class. It should be taken out of that too. There is no point in having a @see link to the same class! :)

The rest looks great, thanks!

Looks great! Thanks! Committed to 8.x.

@er.pushpinderrana: There is a new issue that you might be interested in: #2288499: Action plugin classes need more docs links

It is kind of similar to this one in some ways, but a little different. I tried to write up a good summary of what needs to be done... We will have a lot more like it soon, so I was hoping someone would try to follow the tasks there and then we can make the instructions better for the rest of the issues, if they are not clear. So... If you are interested, that would be great! Thanks for all the recent patches too!
