[MDEP-845] - adding skipColors toggle to list mojo to enable to not write content with colors for an easier parsing

[rmannibucau]

Main issue: the fact the output is not deterministic when dumping content to a file until you always disable colors (otherwise you often have a difference between local and CI outputs).
This PR just adds a toggle to always disable the colors for the output for list mojo.

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MDEP-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MDEP-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the integration tests successfully (mvn -Prun-its clean verify).

Is there a use case for writing control characters to a file? Instead of adding another option, can we skip colors automatically when writing to a file?

This can be solved with mvn -B as well.
