Optimize settings.gradle

[jgrandja]

The script inside settings.gradle dynamically searches for all *.gradle files to determine the list of gradle projects/modules. This script needs to be optimized as the initial filter of excluded files/directories searches in certain directories like src, build and out, which is resulting in a costly search.

It may be as simple as adding '**/build', '**/src', '**/out' in the excludes filter but there may be other options to consider for this optimization.

This change is very sensitive so we need to ensure any changes made do not break the build. Some sort of test needs to be performed to compare the current build with the new build containing the changes.

NOTE: This change should also be back-ported to all applicable and supported branches.

Thanks, @jgrandja! I've removed the milestone for the moment since M2 is currently scheduled for next week, and I'm not certain I'll get this to this ticket by then. Let me know if that causes an issue for you.
