added allowed set flag (#169)

* Implemented validation rules, based on: https://up9.atlassian.net/browse/TRA-3349

* Color on Entry based on rules

* Background red/green based on rules

* Change flag --validation-rules to --test-rules

* rules tab UI updated

* rules tab font and background-color is changed for objects

* Merged with develop

* Fixed compilation issues.

* Renamed fullEntry -> harEntry where appropriate.

* Change green/red logic

* Update models.go

* Fix latency bug and alignment

* Merge Conflicts fix

* Working after merge

* Working on Nimrod comments

* Resolving conflicts

* Resolving conflicts

* Resolving conflicts

* Nimrod Comments pt.3

* Log Error on configmap creation if the user doesn't have permission.

* Checking configmap permission to ignore --test-rules

* Revert time for mizu to get ready

* Nimrod comments pt 4 && merge develop pt3

* Nimrod comments pt 4 && merge develop pt3

* Const rulePolicyPath and filename
