> - FileSystems use static registration using
> *FileSystems#setDefaultPipelineOptions* method.
> - *#setDefaultPipelineOptions* is called either when deserializaing
> SerializablePipelineOptions or during opening of various beam operators.
> - *FileIO#matchAll* is expanded using *Reshuffle.viaRandomKey()*.
> - Reshuffle is implemented using *.rebalance*, that doesn't have a
> "RichFunction" lifecycle, so we need to find another way to register
> FileSystems, as the deserialization may happen before other "rich operators"
> get executed on particular task manager.
> This results in random pipeline fails as the task assignment is not
> deterministic.
> We can workaround this, by registering FileSystems during coder
> deserialization.
