Gh-3149 Add depth limit to NamedOperationResolver

[tb06904]

Adds a configurable depth limit to the NamedOperatationResolver graph hook so that nested named operations are only resolved to a certain depth (set to 3 by default).

This also tidies and refactors the class to simplify the recursion and logic so all NamedOperations will be resolved to their respective OperationChains, with extended debug and logging for if recursion limit is hit so user is aware. If the limit is hit, the NamedOperation is simply left as its class in the chain.
