[Fedora Developer Portal] Call for Contributors for deprecated pages

[Jarek Prokop]

Hi all,

Fedora Developer Portal contains information various information on
technologies that require update from time to time to work with current 
Fedoras.

We have identified a few pages that require updating as they contain old 
information,
outdated (or unsupported) versions of the technology or steps that just 
don't work anymore
on current Fedora (such as installing packages not available in Fedora 
anymore).

If there will be no action for 6 months (=~ Fedora release timeframe), 
the page will be removed
completely from the website. You can spot such pages by a yellow box 
starting with "This page is deprecated!".

tl;dr We need help updating the following pages to contain up-to-date 
steps/information:

* Groovy language page
https://github.com/developer-portal/content/blob/master/tech/languages/groov...

* Cassandra Database
https://github.com/developer-portal/content/blob/master/tech/database/cassan...

* MongoDB database
https://github.com/developer-portal/content/blob/master/tech/database/mongod...

The content sources live in this repo: 
https://github.com/developer-portal/content

Thanks,
Jarek Prokop
