HADOOP-18528. Disable abfs prefetching by default ()
Disables block prefetching on ABFS InputStreams, by setting
fs.azure.enable.readahead to false in core-default.xml and
the matching java constant.

This prevents
HADOOP-18521. ABFS ReadBufferManager buffer sharing across concurrent HTTP requests.

Once a fix for that is committed, this change can be reverted.
