Added action for adding and deleting indexed scripts

[nitram509]

I would like to add two more actions.
One adds indexed scripts, the other deletes them.

As a basis, I've used the reference at:
https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting.html

Feedback is welcome.

The assertions used (contains/null/equals) really fall short of justifying the need for this additional library as we already have junit. Let's stick with junit for now.

@kramer
fest assertions works nicely together with JUnit and Hamcrest.
It offers a readable fluent API and meaningful assertion messages (if tests fails).
May I ask why stick with junit and not extending the possibilities of assertions?

[kramer]

I have nothing against fest I'm sure its as awesome as jest if not more 😄.

Main reason is consistency; having two test classes with a different assert syntax than the rest of the project is just awkward.

[nitram509]

Got it.
I will rework to use JUnit instead of fest.

Also please feel free to add yourself to thanks section in readme :)

@kramer
I've worked on all the things we've talked about.

Would you please have a look at.
Do you miss something?
Feedback is always welcome ;-)

Just two very minor things:

• I think you forgot to revert the pom file :).
• Also forgive me for nitpicking but the list in Thanks section is alphabetically sorted 😊.

[nitram509]

Fixed :-)
