Update all attributes in NWM postprocessing outputs to match current v 3.0 products - [NGWPC 11631]

[sivasankkar]

This PR makes updates to the variable attributes and encoding from templating to combined NWM products. This involves removing xarray generated keys (such as Fill value, chunk sizes) that may conflict with NWM products. The workflow was updated to carry over the NWM attributes right from the templating stage. Other bugs with dimensions of crs variable, feature_ids not adding up in the combined product were also addressed.

Additions

Removals

Changes

• consts.py: added reservoir_assimilated_value to ignored variables list. Added netcdf4 and xarray encoding keys as a list.
• NetCdfProductionManager.py: Added the configuration (cycle type) as a parameter to NOMADs downloads so that it downloads only the user requested products. Assigned the requested cycle as a DataProcessor class variable for easy retrieval throughout the code.
• DataProcessor.py: Added requested cycle as a class variable. Added function to copy the global attributes from the NOMADs reference files to the products. Ensured that the variable attributes are also copied over through all intermediate steps in the post-processing workflow all the way to the combined products. Fixed bugs with crs and time variables to desirable formats.
• utils.py: Added function to copy variable attributes. Updated download function to download only requested products.

Testing

1. Tested with VPU 3N and 3S for CONUS. Alaska, PR and HI dataset for oCONUS.
