Gh-3351: Better GetWalks support on federated POC

[tb06904]

Fixes a few issues for GetWalks when running on new federated POC along with some general bug fixes for it too.
Main changes:

• GetWalks.flatten() no longer gives all the operations get walks will run as this removes all the information about the operation can can be very misleading in an operation chain.
• OperationChainHandler can now apply all operation options on the top level chain to all child operations.
• Bug fix to GetWalks as it did not treat an allEdges: true as a valid hop.
