Migration: Add page about Rockset

[amotl]

About

In the course of the Rockset HTTP API going out of service, others are ramping up their offerings. This page intends to summarize relevant topics from a more technical / developer documentation perspective, this time focused on CrateDB.

The page is also suitable to help people just learning CrateDB to quickly gain a few concise insights without much ado. /cc @kneth

Preview

• Welcome Rockset Developers

Status

• Currently, this is a very early preview. The page certainly needs more attention and sanding, based on your feedback and efforts. Thanks!
• Second Third iteration completed. Suggestions on improving the wording and beyond are much welcome. /cc @surister, @hammerhead, @hlcianfagna, @ckurze, @geragray, @simonprickett

Details

The main job is to index and summarize four other resources (thank you so much!), to add a few more words around them, and to provide general guidance.

Blueprints

Not much derivation happened yet, because we had plenty of content from our pens to remix already. Thank you! So, we are just sharing those links for informational purposes, to enumerate possible blueprints, and to spark further ideas.
