DAS-2339 - Add EASE_row_index and EASE_column_index as required variables.

[sudha-murthy]

Description

Metadata Annotator requires EASE_row_index and EASE_column_index to be part of the request to compute the dimension scales for SPL2SMAP_S granules. They need to be added as required fields in the output of HOSS which precedes the Metadata Annotator in the service chain.

Jira Issue ID

DAS-2339

Local Test Steps

• git clone -b DAS-2339 https://github.com/nasa/harmony-opendap-subsetter

• conda activate hoss

• bin/build-image & bin/build-test & bin/run-test
  All the unit tests should succeed.

  Testing in Harmony in a box

• Run harmony in a box with hoss included in the services

• Do the following request
  http://localhost:3000/C1268429762-EEDTEST/ogc-api-coverages/1.0.0/collections/parameter_vars/coverage/rangeset?forceAsync=true&granuleId=G1268612499-EEDTEST&variable=Soil_Moisture_Retrieval_Data_1km%2Falbedo_1km&skipPreview=true&

The request should succeed and the output file should contain the following variables
/Soil_Moisture_Retrieval_Data_1km/albedo_1km, /Soil_Moisture_Retrieval_Data_1km/EASE_column_index_1km, /Soil_Moisture_Retrieval_Data_1km/EASE_row_index_1km, /Soil_Moisture_Retrieval_Data_1km/longitude_1km, /Soil_Moisture_Retrieval_Data_1km/latitude_1km

PR Acceptance Checklist

• [ X] Jira ticket acceptance criteria met.
• CHANGELOG.md updated to include high level summary of PR changes.
• docker/service_version.txt updated if publishing a release.
• [X ] Tests added/updated and passing.
• Documentation updated (if needed).

DAS-2339 AC says SMAP L3. Is it both SPL2SMAP and SPL3SMAP?

AC:
'The requested output from HOSS should contain EASE_row_index and EASE_col_index for SMAP L3 collections and the regression tests should be successful'

[sudha-murthy]

We can do it for all collections. But we decided to only implement it this way for SPL2SMAP_S. The other collections uses the index ranges from the history attribute to determine the subset index.

Line 1322-1333 is similar to Line 1347-1357. Declare on line 1259 and reuse the code?

I have some very minor comments but it looks good overall.
Unit tests ran successfully.
My harmony-in-a-box is broken right now so I wasn't able to run the request in the test instructions, but I'm satisfied with Vu's testing of it.

[joeyschultz]

Thanks for the updates Sudha. I reran the unit tests after the dmr file update and they still pass. Marking as approved.
