Enhancements

What this PR does / why we need it:

This PR is used to support SPD's resource portrait plug-in. The main changes include adding a new configuration type ResourcePortraitConfiguration and expanding SPD semantics.

• Although ResourcePortraitConfiguration is defined in the form of CRD, it is only used to inject into the RawExtension of SPD, and there is no need to create the resources corresponding to the CRD in the cluster.
• SPD's AggPodMetrics field adds a Scope field, whose semantics are similar to Scope in NPD, for use by plug-ins. A plug-in can freely create multiple Scopes to distinguish different indicator sequences. At the same time, Aggregator field extends the AggregatorRaw type to represent temporary data generated by the plug-in.
