DYN-7409 Execution session preference file path

[twastvedt]

Purpose

Add the current preference file path to Execution Session to make it available to nodes.

We'd like this for the GraphEngine node in particular, to allow us to match the current preferences in the Dynamo instance that we spin up.

So thinking about it a bit more- is there any reason not to make the entire path manager available?
Or maybe a readonly copy of the paths in the path manager?
