Kotlin DSL friendly overall tasks

[Vampire]

You have the closeAndReleaseStagingRepository task (which should probably better be called closeAndReleaseStagingRepositories).
This task is always registered no matter which repositories are configured.
This is good, as then we also get type-safe accessors for the Kotlin DSL for it.
And as typically only Maven Central is configured, this is also a perfect replacement for the closeAndReleaseSonatypeStagingRepository task that does not get accessors generated.

The problem is, that I don't want to do close and release coupled.
I do the closing when doing also other publishing tasks like creating the GitHub publication.
Only after also all other tasks were successful, I want to release the repository.

So I would welcome closeStagingRepositor(y/ies) and releaseStagingRepositor(y/ies) to conveniently wire them using Kotlin DSL.

Looks like this issue is actually not so much about Kotlin DSL, but somewhat duplicates #215 and #134 (and is quite the opposite of #77).

Not really @sschuberth.
This is about adding summary tasks for only closing and only releasing like there is one for closing and releasing together.
This is not too tightly related to Kotlin DSL, but makes the usage better in Kotlin DSL as described above.

#215 is about the standalone closing and releasing somehow having some problem
#134 is about the possibility to upload multiple things in multiple Gradle runs and then do a close and release for them together in a separate run
#77 is not at all opposite to this request, it just requests some combination tasks that that combine publishing and closing which is totally independent of this request

Well, while we are at it, I implemented it in #285 :-D

Good luck with getting it merged (honestly, no sarcasm here).

I think this broke the Mockito build, did it not? mockito/mockito#3259

* What went wrong:
A problem occurred evaluating script.
> Task with name 'closeAndReleaseStagingRepository' not found in root project 'mockito'.

We were using rc.1 before. If this is considered a breaking change, then we can figure out how to mitigate. Otherwise, we probably want to fix it here.

I think you need to go plural on "repositories". @szpak you should mention the breaking changes explicitly in the notes.
