Decide what to do with UnparseableDescriptors while synchronizing from another instance
Let's find out, if a code change is needed or things are fine as they are.
Current situation when one CollecTor fetches data from another CollecTor:
Metrics Lib cannot parse the fetched content, provides an object of UnparseableDescriptor
, and CollecTor simply ignores this object as unknown (only logs on trace level).
During normal collecting an unparseable descriptor is stored anyway.
