Add checkstyle for non-inclusive terms

[peternied]

Description

To aid in detection and removal of non-inclusive terms, adding a
checkstyle error when they are detected. When we are ready to remove
all these terms from the codebase we will set these checks to error
level.

Issues Resolved

• Related to Deprecate the "Master" nomenclature #1664

Updated build output

Since all errors are ignored by default, now the checkstyle output is much easier to parse, here is an example of the output with this change.

@davidlago Done!

@.tlfeng Thanks for driving this effort, I would strongly recommend adding a mechanism to ensure we have removed all of these terms. By onboarding a separate check style workflow that can be created and run automatically by plugins it ensure compliance and lets you capture metrics charting the progress to zero.

I've created a couple of checkstyle rules in this PR for the security plugin #1782
