adds cbrfc_wsv_esp data to local warehouse for crmms test locations

[samland1116]

• Restructures the warehouse/local dir to include a utils folder to store the setup_utils.py and any other ingest specific utils. These utils will move to a prefect workflow but are stored here temporarily to avoid blocking progress on frontend-development

• CBRFC WSV ESP Test Data:

  • adds notebook setup for CBRFC water supply volume ESP forecasts for three CRMMS locations where we had a crosswalk
  • queries the CBRFC forecast data for an archived period to compare to USGS volumes/NWM-retrospective volumes for an overlapping period (2016-01-01 to 2022-11-30)

Will transition into prefect workflow as opposed to this scratch-work implementation once we have the full locations list

Closes #20

Mostly same comments at #68

Overall I think we need to coordinate the secondary IDs, crosswalks and variable names.

I also think we want to keep things split up so domain adding code separate from fetching code, etc. but we can evolve the process as we go as long as we commit to doing so and continuing to refactor.

Just a note - don't need to address here: Some of this code loading the domains, locations, crosswalks, etc. is really data migrations (vs database schema migrations) - ultimately, we probably need to figure out a better pattern for handling "data migrations" which seems to be a pain point across many projects.
