improve operation deserialization speed

Pieter Eendebakrequested to merge
peendebak/quantify-scheduler:feat/operation_deserialization into pieter_feat_operation_deserialization

Explanation of changes

The locate method is expensive in the deserialization of an Operation. This PR uses the standard functools.lru_cache to cache the result.

The number of items in the cache is small, so there is no need to manage clearing the cache.
