WS-2755: Cube ingestion template fixes
This contains a few fixes to the workflow templates and ingest_envoy for coarse cubes found during integration testing:
- Properly sets the path to the installed
pimscacheand the path to the version of Python it expects - Switches to using the
data_srcparameter instead of the reserveddata_locationparameter to not write to the VLASS spool directory - Fixed a bug with the indexing message using a parameter not set in cubes
- Stealing ownership of the
accepted_planes.txtfile from tomcat before copying it to the cache (it was preventing us from setting the permissions on the cache directory)
