There have been quite a few discussions and a few attempts to make astropy.modeling a useful modeling / fitting framework for us, but they all stalled (the last one being astropy/astropy#3786 by @nden).

So now we've decided to use Sherpa for Gammapy and this PR is a first step in that direction by removing the PoissonLikelihoodFitter class that I added a few years back when astropy.modeling added fitters.

Just in case someone wants to implement a Poisson likelihood fitter in Astropy ... this was the latest version of the class in Gammapy: cdeil@8108359
