Audit scoper for storage data model

https://blueprints.launchpad.net/watcher/+spec/audit-scoper-for-storage-data-model

Problem description

Storage cluster data model was introduced in Pike cycle. Since the model is different from compute data model, we need CDM scoper for storage cluster data model.

Use Cases

As a Watcher user, I want to restrict scope of storage cluster data model.

Proposed change

This spec adds storage cluster data model scoper which can restrict the followings.

• storage availability zone
• volume type
• exclude
  • volume
  • storage pools
  • volumes of project

For adding it, we will implement as compute cluster data model scoper is implemented.

• Add JSON schema in cinder cluster data model collector.
• Add storage audit scope handler which overrides BaseScope class and implements get_scoped_model method.

Alternatives

Strategy developer can restrict storage cluster data model in a strategy respectively.
