Review request for Flume.
Changes
-------
Added note about reading stderr of a sub-process is required.
Summary (updated)
-------
1) Allows users to configure a restart flag and sleep interval for the
ExecSource should the command exit.
2) Currently no one is reading standard error for the sub process. It is not
ignored like the documentation suggests. If the command generates enough stderr
to fill it's buffer, it will be blocked until someone reads that buffer. A
thread is added which by default reads and throws away stderr. If a flag is
turned on it will logstderr. This kind of flag can be very useful when
debugging why a command is not outputting the expected data.
This addresses bug FLUME-979.

Testing
-------
A test for the restart flag and restartThrottle flag were added. All unit tests
pass.
