framework/db: use HikariCP as default and improvements (#9518)
Per docs, if the mysql connector is JDBC2 compliant then it should use
the Connection.isValid API to test a connection.
(https://docs.oracle.com/javase/8/docs/api/java/sql/Connection.html#isValid-int-)

This would significantly reduce query lags and API throughput, as for
every SQL query one or two SELECT 1 are performed everytime a Connection
is given to application logic.

This should only be accepted when the driver is JDBC4 complaint.

As per the docs, the connector-j can use /* ping */ before calling
SELECT 1 to have light weight application pings to the server:
https://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-j2ee-concepts-connection-pooling.html

Replaces dbcp2 connection pool library with more performant HikariCP.
With this unit tests are failing but build is passing.
