Beam 2.28.0 objectReuse and fasterCopy for FlinkPipelineOption

[Eleanore Jin]

Hi community,

I am upgrading from Beam 2.23.0 -> 2.28.0, and a new FlinkPipelineOption is
introduced: fasterCopy.

Can you please help me understand what is the difference between the option
objectReuse vs fasterCopy?

Thanks a lot!
