Add an Environment variable to expose pass extra classpath #814
Description
Is your feature request related to a problem? Please describe.
Currently the polaris-service script sets the CLASSPATH inside it. As a developer I would like to add some extra paths to Classpath via an external variable like POLARIS_CLASSPATH which can then be appened to CLASSPATH like CLASSPATH="$CLASSPATH:$POLARIS_CLASSPATH"
Describe the solution you'd like
Expose a variable named POLARIS_CLASSPATH and update the polaris-service to append it to the CLASSPATH like CLASSPATH="$CLASSPATH:$POLARIS_CLASSPATH"
Describe alternatives you've considered
Currently when running via the container I used to do the sed hack like the following to append to the classpath
sed -i '/CLASSPATH=.*/{p;s/.*/CLASSPATH="$CLASSPATH:\/conf"/}' /app/bin/polaris-service
