Dynamic catchain delays, state serialization improvements (#1140)

Browse source 
* Validator improvements

* Fix cancelling state serialization
* Disable state serializer on all mainnet validators
* Flag --catchain-max-block-delay-slow

* Set default catchain-max-block-delay to 0.4, delay-slow to 1.0
