Description

Is your feature request related to a problem?

Per the OpenTelemetry specification on Views (in the Metrics SDK). Views SHOULD support the ability to configure an exclude list for attribute keys.

Additionally, implementations SHOULD support configuring an exclude-list of attribute keys. The exclude-list contains attribute keys that identify the attributes that MUST be excluded, all other attributes MUST be kept. If an attribute key is both included and excluded, the SDK MAY fail fast in accordance with initialization error handling principles.

Describe the solution you'd like

Add support for an exclude list for attribute keys for Views.
