feat: allow to override ORM connection properties

[yurem]

ORM should use environment/java variables with same names to override ORM configuration properties.

Also it should use environment variables like CONNECTION_URI to override properties like connection.uri and connection-uri

[yurem]

Here is example to override connection.uri from /etc/default/jans-auth:

java variables:

JAVA_OPTIONS="...-Dconnection.uri=jdbc:postgresql://localhost:5432/jansdb..."

env variables

export CONNECTION_URI=jdbc:postgresql://localhost:5432/jansdb

Hi @yurem

I am updating documents for these changes.

I have a quick question: The steps above will change the property value only for jans-auth module.
But same has to be done for all the other modules which use ORM so that all Janssen Server modules point to the same DB. Is this understanding correct?

@ossdhaval its actually the opposite in VM. If you pass that env globally it will change for all the modules.

[yurem]

right, it depends on scope where you export env properties. Global properties will be used in all jans app. If you need to export them for specific app you can use /etc/default/jans-xyz for example
