Add shiro configuration to application.yaml

[Sherpard]

Shiro.ini configuration is currently inaccessible within software configuration.

Currently you have to create an AbstractModule Annotated with @Install annotation and bind the constants on the configure() method An example could be found at: Hub security module

It would be nice to have that configuration as an an option in application.yaml

I have already defined some useful Shiro options in the newest version (3.3.0) but I agree we could provide a way of specifying arbitrary Shiro options in the configuration.
