GOAL:
As Trident dynamically manages persitent volumes & bring lots of goodness to the app level.

However, this freedom can lead to quickly feel up the storage backend, especially if the user does not tidy up his environment...
A good practice is to place some controls to make sure storage is well used.

This scenario will guide you through different ways to add control to your environment
1. Kubernetes parameters
2. Trident parameters
3. ONTAP parameters
4. Mixing them all
5. What about CSI Snapshots ?
