David Roberts 979d232faa [ML] Set jobs to FAILED state if C++ process dies unexpectedly (elastic/x-pack-elasticsearch#876)
Previously a `kill -9` on the `autodetect` process associated with a
job would leave the job in the OPENED state.

Now if the C++ process dies before a request to close the job is made
then the job state is set to FAILED.

For this purpose C++ process death is defined as end-of-file on the
log stream.  (Technically it would be possible to get end-of-file on
the log stream while the C++ process was still running, but this
would also represent an unexpected and undesirable situation.)
