HADOOP-15407 adds a new FileSystem implementation called "ABFS" for the ADLS Gen2 service. It's in the hadoop-azure module as a replacement for WASB. Filesystem semantics should be the same, so skipped tests and other behavior changes have simply mirrored what is done for ADLS Gen1 by default. Tests skipped on ADLS Gen1 due to eventual consistency of the Python client can be run against ADLS Gen2.
