Commit 4e87a80fae86c5775a5f35607806fee287b3797a in impala's branch refs/heads/master from Michael Smith

IMPALA-9488: Add metrics for EC reads
Adds metric tracking erasure-coded bytes read. Adds ScanRange::TestInfo
to pass file info through calls of AllocateScanRange so it's easier to
add erasure coding as another piece of file info.
Adds a test to verify that the expected number of bytes are read for
existing read metrics and the new `erasure-coded-bytes-read` metric when
doing a select.
