In order to do -C-RU-D- buckets we need a new API that can handle PUT to update the current 'platform' bucket so the user can add any additional projects they choose to the platform cost bucket.

MUST

• User should be able to add other projects (that can be multi-clustered) to the “platform bucket” (non default projects aka Openshift-* or Kube-*)
• User should be able to remove projects that they’ve put into the “platform bucket” (non default projects aka Openshift-* or Kube-*)
• View a list of projects that are denoted into the “platform bucket”
• Use same permissions as settings page (RBAC)
• Recalculate cost for current month (same as cost model)

Should

• Support “string*” addition of projects

Will Not

• User cannot include regular expressions
• Users can not remove default OpenShift projects
• There will only be a “Platform bucket” to add projects to - no multiple buckets (for this feature anyway)

Note:
In order for the user to get a list of projects for populating the platform bucket we can make use of the resource-types endpoint.
