Use cycle-aware cache for GCP cloud metadata

[orouz]

Motivation

we currently initiate a cache in the GCP asset inventory provider to hold cloud account metadata:

cloudbeat/internal/resources/providers/gcplib/inventory/provider.go

Line 178 in ded46ca

crmCache: make(map[string]*fetching.CloudAccountMetadata),

but if the project/org names changed between cycles (unlikely, but possible) we'd still get the old values. we still need the cache itself, as resources tend to have same project/org names, but we need to make sure the values are fresh.

Definition of done

• make sure we get fresh values for cloud account metadata
