Here we update the eth and snap protocol test suites with a new test chain, created by the hivechain tool. The new test chain uses proof-of-stake. As such, tests using PoW block propagation in the eth protocol are removed. The test suite now connects to the node under test using the engine API in order to make it accept transactions. The snap protocol test suite has been rewritten to output test descriptions and log requests more verbosely. --------- Co-authored-by: Felix Lange <fjl@twurst.com>
