Add optional MySQL connection string options

[lobbin]

Affected Puppet, Ruby, OS and module versions/distributions

• Module version: 4.0.1

What are you seeing

The jira module have a static string of options,
jdbc:mysql://localhost:3306/jira?useUnicode=true&characterEncoding=UTF8&sessionVariables=default_storage_engine=InnoDB

What behaviour did you expect instead

I'd like to add an option for us to define for instance, useSSL
jdbc:mysql://localhost:3306/jira?useUnicode=true&characterEncoding=UTF8&sessionVariables=default_storage_engine=InnoDB&useSSL=false

Never mind, I realised I can use the dburl setting.
