    [FLINK-6770] Add excludeSerializersFromCheckpoints to ExecutionConfig

    This PR adds a flag to indicate whether or not type serializers should be included in checkpoints.
    
    This configuration should be respected by all composite serializers, as well as the serialization proxies for operator and keyed state backends. If the flag is `true`, then only the serializer's config snapshot should be written, instead of both the serializer _and_ the config snapshot.

> A {{excludeSerializersInCheckpoints}} setting should be added to the configuration.
> Composite serializers that write the nested serializers into checkpoints can then respect this setting when writing their configuration snapshots. Currently, the functionality is already in there for the composite serializers, but the flag is right now hardcoded to {{false}} because there is no config available for the behaviour yet.
