OFBIZ-13412 - Updated the following:

 Based on the recommendations to get optimised performance, changing the pool-minsize value to 2 same as we have this parameter value for Postgres and MySQL. And adding CACHE_SIZE=65536 (64MB) for the h2 URI as this is also recommended for optimised performance of the database.
