[FLINK-6478] [doc] Document how to upgrade state serializers
This PR adds documentation on how use custom serializers for managed, as
well as handling upgrades to the serializers.
We could probably also consider restructuring the "Working with State" page
to be a navigation to nested subpages that each cover different topics on
working with state, e.g. "Programming API" and "State Serialization", as
stuffing all this new detail into a single page might be a bit too overwhelming
for new users.

>
> There needs to be a documentation that explains how to use the new serializer
> upgrade APIs in {{TypeSerializer}}, and how the methods work with
> checkpoints. This documentation should probably be placed under "Application
> development --> Streaming --> Working with State".
> Ideally, it should also come with a minimal example for users that perhaps
> use serialization frameworks that already have built-in backwards
> compatibility (such as Thrift).
