https://issues.liferay.com/browse/LIFERAYQA-12161

Hi Brian. I've added another commit on top of what I sent in the previous pull.

1. I split up the plugins deployment into 2 targets and called those targets in "run-simple-server" -> "deploy-required-plugins" and "deploy-regular-plugins"
2. I added comments in "deploy-regular-plugins" to indicate what the target is doing

This will not cherry-pick into ee-6.1.x/ee-6.1.30 because 6.1 does not require marketplace-portlet like 6.2 and master do. So ee-6.1.x/ee-6.1.30 will not have "deploy-required-plugins".
