[BEAM-1337] Infer state coders
----
> Use our coder infrastructure for coders for state
> -------------------------------------------------
>
> Key: BEAM-1337
> URL: https://issues.apache.org/jira/browse/BEAM-1337
> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-core
> Reporter: Kenneth Knowles
> Assignee: Aviem Zur
> Priority: Minor
>
> Today the user must explicitly provide any coders needed for serializing
> state data. We'd rather use the coder registry and infer the coder.
> Currently all factory methods in {{StateSpecs}} take a coder argument. For
> example:
> {code}
> StateSpecs.value(coderForT);
> {code}
> We could leverage the coder registry and provide different overloads:
> TypeDescriptor:
> {code}
> StateSpecs.value(typeDescriptorForT);
> {code}
> Reflection:
> {code}
> StateSpec.value();
> {code}
