    [BEAM-2005] Move getScheme from FileSystemRegistrar to FileSystem

    Note that I needed to update FileSystems to instantiate the FileSystem(s) upfront instead
of remembering the mapping from scheme to registrar during "registration" of the PipelineOptions.

> Beam's FileSystem creates an abstraction for reading from files in many different places.

> We should add a Hadoop FileSystem implementation (https://hadoop.apache.org/docs/r2.8.0/api/org/apache/hadoop/fs/FileSystem.html)
- that would enable us to read from any file system that implements FileSystem (including
HDFS, azure, s3, etc..)
> I'm investigating this now.
