[WIP] Fake bls at runtime (#735)
* Initial implementation of runtime bls skipping.

Add libnfuzz skipBLSValidation handling, check that it propagates.

* Rename skipBLSValidation -> skipBlsValidation, start skipStateRootValidation
* Replace skipValidation flags with more granular flags.

Also added skipBlockParentRootValidation flag
Mainly replaced with skipBlsValidation but also StateRoot or
BlockParentRootValidation flags where appropriate.

* Adjust interop test to pass when skipping merkle validation.
* Stop skipping validation for mainchain_monitor.
* Remove comment.
* Also skipMerkleValidation for test_beacon_chain_db.

Hotfix: disable the bootstrap node connectivity check
This used to behave properly before the rebase, but currently
it forces the bootstrap node to exit, because it ends up being
launched with an ENR list telling it to connect to itself.

The root cause will be investigated in a follow-up PR.
