Add HikariCP connection pool for MySQL (#86)

Browse Source 
* Add HikariCP connection pool for MySQL

* Make code more compatible with connection pooling

- Remove connection caching in Process/Consumer
- Use try-with-resources to make sure Connections always get closed, even in
  when an Exception occurs.

* Disable SSL for MySQL
