AST Parsing robustness

[charles-turner-1]

The AST listener uses config.yaml to listen for calls & send telemetry when the right calls are found, eg.

intake:
  catalog:
    - esm_datastore.search
    - DfFileCatalog.search
    - DfFileCatalog.__getitem__
payu: 
  run: 
    - Experiment.run
  restart:
    - Experiment.restart

esm_datastore.search will listen for that function call, and post telemetry to .../intake/catalog

I need to double check that this doesn't depend on how things are imported - eg. will the following be caught correctly:

intake:
  catalog:
    - esm_datastore.search
    - DfFileCatalog.search
    - DfFileCatalog.__getitem__
+  builder:
+    - AccessOm2Builder.build
payu: 
  run: 
    - Experiment.run
  restart:
    - Experiment.restart

Questions to confirm:

1. Will inheritance break this? Eg. if AccessOm2Builder.build is a method defined on a parent class, is this still going to work?
2. Will we get issues depending on the import style, eg.

from access_nri_intake import builders
...
builders.AccessOm2Builder.build()

Will this still be caught as if we had performed the following?

from access_nri_intake.builders import AccessOm2Builder
...
AccessOm2Builder.build()

TLDR; yes.

Fixes incoming.
