aggrid 8.x-1.0-alpha25

All are potential breaking changes. aggrid_diff module should be disabled before upgrading to this alpha.

Some basic entity testing items were added, along with some separate new aggrid specific roles.

Issue Queue:

Issue #3028726 by mferanda: Need to add PHPUnit Tests
The potential break from this issue is the adding of new roles. I'm not really sure I should call it a breaking change since it just allows for some flexibility outside of only the administrator role for aggrid management. Of course, I only recommend high level users for aggrid config entity and aggrid settings access.

Issue #3051860 by mferanda: Move diff into module
After review, I decided there was no reason to keep this separate. The diff necessary pieces are moved into the main module and this is removed.

Issue #3050326 by mferanda: Remove percent items from parserTypes
I discovered some potential issues when using a percent as a parserType. However, while trying to fix the issue, I also realized this parserType is no longer needed. Basically, percent was added because I needed a decimal that provided a simple constraint from 0 to 100%. So... I'm removing it! If you're using this as a parserType, just switch over to dec and apply a constraint. (See documentation for constraint instructions)
