Develop a method to pull all variables linked to a feature

PROBLEM

How to handle when an MP or other feature is missing/delete/disappears from VAHydro? See email titled: How to handle missing MP on live? - Doswell WTP Facility & North Anna River Intake

We need to establish a workflow to follow for retrieving props/ts data from one feature on a VAHydro site and pushing it to another.

Long-term Solution:

• option 1: rewrite dh_get_dh_propts_tree in r script
• option 2: View and Rscript combo
  - Make view that runs dh_get_dh_propts_tree dhmodule function and simply returns pid
  - R script uses pid to pull all fields using REST get_props/ts function
  - Reset all PID values so they don't override anything when pushed
  - Pushes updates to VAHydro via rest
  - Note: RB and JM are leaning towards this option as it leverages a dhmodule function that already exists
• Test Node for dh_get_dh_propts_tree is at dh/node/65

We'll want this completed before the May 2020 QA Cycle when we set the 5 Year Average Property (wd_current_mgy).

@jmineva -- did we essentially sort this out? If so, can you leave a link to the most up to date code you have for ding this and then close this? Thanks!
