User should be able to point to a hibernate configuration file during setup

Current Situation

• JobScheduler setup creates a hibernate configuration during initial setup with user selected options.
• In some cases such as MSSQL Server 2016, the hibernate configuration can have many advance database connection properties.

Desired Situation

• JobScheduler setup should provide an option to point to an external hibernate configuration file.
  • The external hibernate configuration will not check against the Hibernate DTD.
  • The following properties are required
    • hibernate.connection.driver_class
    • hibernate.connection.url
    • hibernate.dialect
  • The following properties are optional
    • hibernate.connection.username
    • hibernate.connection.password
  • Missing properties for connection pooling will be added. Theses are
    • hibernate.c3p0.minPoolSize
    • hibernate.c3p0.maxPoolSize
    • hibernate.c3p0.initialPoolSize
    • hibernate.c3p0.acquireIncrement
    • hibernate.c3p0.maxIdleTime
    • hibernate.c3p0.maxConnectionAge
    • hibernate.c3p0.idleConnectionTestPeriod
  • Already existing properties are not removed or overwritten.
