Subject: [PATCH] FINERACT-796

Use Hikari instead of Tomcat Connection Pool
 - Created hikari connection pool bean
 - Configured connection parameters to match hikari
 - Removed tomcat-jdbc and dbcp
 - Remove unused classes
 - Add Hikari to logback
 - update hikaridatasource bean

closes https://issues.apache.org/jira/browse/FINERACT-796

remove hikaricp import from gradle files

more specific bean config

- Set up datasource properties
- Cleanup unused classes
- Add hikari to logback
