clearing the executor authentication token from the task environment

[James Peach]

Hi all,

In https://issues.apache.org/jira/browse/MESOS-8140, I'm proposing that we 
clear the MESOS_EXECUTOR_AUTHENTICATION_TOKEN environment variable immediately 
after consuming it in the built-in executors. This protects it from observation 
by other tasks in the same PID namespace, however I wanted to verify that 
no-one currently has a use case that depends on this. Currently, the token is 
inherited to the environment of tasks running under the command executor (i.e. 
not to task group tasks).

Eventually we would add a formal API for tasks to access the executor token in 
MESOS-8018.

thanks,
James
