1605e6ff13
Based on current implement, some metadata can't be extracted by pollster, such as architecture, reservation_id, ephemeral_gb, etc. This patch will try to get those metadata if we can and remove those metadata what can't be pulled by pollster. Fixes bug 1202749 Change-Id: I1f08c4eaa1cfacb612097cd0e90629d682f8acc9
