Code Issues Proposed changes

Add scope prefix in configuring host aggregates

Browse Source 
Using unscoped key pairs will cause conflicts between
ComputeCapabilitiesFilter and AggregateInstanceExtraSpecsFilter.
And that conflicts lead to return 0 hosts of
ComputeCapabilitiesFilter.

This patch adds 'aggregate_instance_extra_specs' scope when
configuring host aggregates to avoid above conflicts.

Closes-Bug: #1445285
