In BA Operator is not possible to set size of Business Central default Persistence Volume. It's not possible to set it via Operator UI and it's not possible to do it in KieApp yaml as well. Is expected that this should be possible in both places.

Default persistence volume stores data in /opt/kie/data folder.

As some projects can be bigger and also m2 dir repository can be set as persisted, there can be needs for bigger size of persistent volume.

Right now we can only set `storageClassName`. Size configuration for PV is only allowed for Kie Server DB's volumes.
