Don't log SSL truststore password

[msteiger]

Currently, the keystore passwords are logged when the log level is set to debug for HikariConfig. The passwords should be masked though.

• The PostgreSQL driver uses sslpassword (https://jdbc.postgresql.org/documentation/use/)
• MariaDB uses trustStorePassword (https://mariadb.com/kb/en/using-tls-ssl-with-mariadb-java-connector/)

for client-side SSL truststores in JDBC URLs. These passwords should not be logged when DEBUG logging is enabled.
