PORT-8772 | Add filter to opencost integration

[lordsarcastic]

Description

What:

• Added filter params to Opencost cloudcost and Kubecost cloud and kubesystem kind.
• Implemented separate config for v1 and v2 selectors for Kubecost cloud and kubesystem kind

Why:

• Opencost and Kubecost added the filter feature which is a much more powerful aggregation parameter as opposed to the existing fields, adding this field allows users to be much more flexible with what data they ingest into Port
• The Kubecost integration, while currently on v1 as set:

KUBECOST_API_VERSION_1 = "v1"

Uses the same selector to handle filters for both kubesystem and cloud kinds which should be separate. In addition, the params accepted by v1 is not the same as that on v2; this applies to both kinds.

How:
To address these needs, different selectors are defined for each kind and for each version and can be used when needed
