Gammapy version 0.8 release

[Christoph Deil]

Dear colleagues,

we are happy to announce the release of Gammapy version 0.8.

Gammapy is an open-source Python package for gamma-ray astronomy built on Numpy and Astropy.
It is a prototype for the Cherenkov Telescope Array (CTA) science tools,
and can also be used to analyse data from existing gamma-ray telescopes.

This release features major improvements to maps, modelling and tutorials, now including 3D analysis.
It contains many other additions, improvements and bug fixes.
