Validate final type after URL eval

[jmosbacher]

If type is given, validate the config type after URL evaluation.
Also added the run_id to the cache key.

Thanks @jmosbacher . Are codes that can change the results only def validate_type?

[jmosbacher]

@dachengx Oh right, sorry about that. I ran auto formatting so there are a bunch of formatting changes not really relevant to the actual change.
The validate_type and fetch methods indeed include the actual "logic" changes.
I am a bit on the fence whether we should warn when the type is incorrect or raise an error. Any opinion?

[dachengx]

No problem. Since type does not influence lineage, maybe we can raise errors and also modify the current code if needed.

[jmosbacher]

Ok, I will switch it to raise an error.

Looks great. Thanks @jmosbacher .
