[Feature Request]: Support Java 14 records in SchemaCoder

[Gadiguibou]

What would you like to happen?

The current JavaBeanSchema and JavaFieldSchema do not support working with Java 14 records by default because the record components are private final and the accessor methods do not conform to the Java bean convention (field() instead of getField()).

A new schema class for the schema coder could be created to support coding Java 14 records. Java records are especially well suited as intermediate data structures in beam pipelines because of their automatically generated hash, equals, and toString methods as well as their immutability. This would reduce boilerplate which inevitably causes issues down the line as everyone reimplements the same methods with varying degrees of correctness and uses code generation tools with poorly documented semantics.

I just wanted to mention that all Java Beam artifacts are still built with Java 8. So I'm not sure that it's possible to do until Beam will move to Java 14.
