HARMONY-1995

Description

As a user, I want Harmony to handle service a response that indicates that a result contains no data.

Local Test Steps

Modify harmony-service-example to create nodata warnings for specific granules to facilitate with the testing. e.g. add from harmony_service_lib.exceptions import NoDataException at the top and the following to around line 98 of transform.py in harmony-service-example:

if asset.href == 'https://harmony.uat.earthdata.nasa.gov/service-results/harmony-uat-eedtest-data/C1233800302-EEDTEST/nc/001_00_7f00ff_global.nc' or asset.href == 'https://harmony.uat.earthdata.nasa.gov/service-results/harmony-uat-eedtest-data/C1233800302-EEDTEST/nc/001_07_7f00ff_north_america.nc':
   raise NoDataException("Ain't got no data")

to simulate two nodata warnings for the first two granules in this harmony request:
http://localhost:3000/C1233800302-EEDTEST/ogc-api-coverages/1.0.0/collections/red_var,blue_var,green_var/coverage/rangeset/?subset=lat(20%3A60)&subset=lon(-140%3A-50)&outputCrs=EPSG%3A31975&format=image%2Fpng&maxResults=3

You can simulate the entire job's work items all have nodata warnings or a single nodata warning error by changing the maxResults to 2 or 1. And feel free to test with chains with multiple services.
