Review request for mesos and Joseph Wu.


Fix outstanding issues.

Bugs: MESOS-6003

Repository: mesos

Description (updated)

Adds the external process container logger. This functions like the
logrotate container logger, but instead calls a custom host binary
(or script) and passes the executorInfo as JSON via environment
variables. This makes it very easy for users to configure custom
logging solutions, without needing to write and maintain logging

Tests passing and complete.

Adds ContainerLoggerTest.EXTERNAL_RecieveEnvironment which tests all major parameters of the

A synthetic external container logger is provided by the script tests/
which is setup to fail if any important output is unavailable to the logging process. 

The other basic checks are duplicated from the Logrotate container logger, from where this
change inherits a lot of its code.
