Modify run_tests.sh to support PostgreSQL

Modify run_tests.sh to run unit tests with PostgreSQL. Fix a number of connection pool and deadlock related issues in the unit tests. Fix DB clean up routine to remove records in the correct context and order. Change-Id: If88c00a326c025af885d061ca95588939195b7c5 Implements: blueprint run-unit-tests-on-postgresql
