Subject [jira] [Comment Edited] (YARN-6374) Improve test coverage and add utility classes for common Docker operations.

------------------------------------------------------------

As part of the draft patch for YARN-5366, utility classes were added as a facade to reduce
the effort needed to run Docker related commands. In an effort to keep that patch manageable,
and due to change in scope, the utility classes have been extracted into a separate patch.
These utility classes will be useful as part of the container signaling and image localization
work as well. I'll take this one.

> Currently, it is tedious to execute Docker related operations due to the plumbing needed
to define the DockerCommand, writing the command file, configuring privileged operation, and
finally executing the command and validating the result. Obtaining the current status of a
Docker container can also be improved. Finally, the test coverage is lacking for Docker Commands.
