Break the current operator's configuration into custom and managed pr…

…operties (#367)

* Initial commit

* integrating comments: introducing ObjectEnsurerWithPlatform and ObjectCreatorWithPlatform

* Removing fewe more unneeded references to platform

* reviewed workflowProjectHandler. removed user props from managed props

* fixed unit tests

* workarond for failed discovery options

* fixed broken unit tests

* fixed mutator for user props

* reviewed hashing function

* Anticipating deactivation of broken e2e test

* integrating comments: removing unneeded comment

* adding discovered value to properties whose value mathes the service discovery pattern

* removed unused package common_test

* Renamed managed props visitor and reviewed description of NewAppPropertyHandler
