Assertoor

[kamilchodola]

Added a new testing tool from EF called "Assertoor" https://github.com/ethpandaops/assertoor and also connected it with a tests collection from https://github.com/ethpandaops/assertoor-test using a dynamic script which will automatically add new tests whenever such ones appear.

Currently filtered out a few recommended by EF DevOps folks.

In future it is a matter of being parallelized and subset of tests to be run on each commit (for example block production verification).

NOTE:
Currently using a fork of assertor-test https://github.com/kamilchodola/assertoor-test) because waiting for ethpandaops/assertoor-test#10 to be merged - but there are some doubts about some edge cases so until then will keep it like this.
