The workflow XML fails to run if ensemble verification is set to TRUE and DO_ENSEMBLE=FALSE

[JeffBeck-NOAA]

Description

If either ensemble verification task (RUN_TASK_VX_ENSGRID or RUN_TASK_VX_ENSPOINT) is set to TRUE in the config.sh file, but DO_ENSEMBLE is not set to TRUE, the XML will fail to validate when the launch script is executed:

FV3LAM_wflow.xml :: Error: Element workflow failed to validate content at FV3LAM_wflow.xml:107.

Steps to Reproduce

Set either RUN_TASK_VX_ENSGRID or RUN_TASK_VX_ENSPOINT to TRUE, but DO_ENSEMBLE to FALSE in the config.sh file, then run the launch script in the run directory.

Solution

Add a check to the generate_FV3LAM_wflow.sh script to ensure that if either ensemble verification is activated in the config.sh script, DO_ENSEMBLE is also set to TRUE.
