[atlas] RIPE Atlas roadmap has a new home

Dear Atlas community,

[apologies for duplicates]

we determine the roadmap for RIPE Atlas together: based on RIPE NCC 
internal plans and ideas, and on your wishes and suggestions & needs.

After publishing the incremental updates to the roadmap in
the RIPE Labas articles and presentations,
we now have a permanent location for the RIPE Atlas roadmap:

http://roadmap.ripe.net/ripe-atlas/

It is part of the listing of a few RIPE NCC services and their plans.

We publish the features in 4 categories:
* recently delivered
* in progress
* planned
&
* requests

We will keep updating this page, every time when one of the features 
move from "in progress" to "delivered", and so on.

Next steps are
* to add more details about all of those listed features,
* to take on your comments, feedback, suggestions, and prioritize those 
that are only "requested", so that we can understand what exactly the 
feature means, and to move it to the "planned" category.
* do consider automating the expression & collection of feedback
