[loadable firmware] I&M handling in application shall be possible even if database configuration is used

If loadable firmware is used and configured with a databse the I&M data is always handled by the firmware. It is not possible for the application to influence the I&M data at all.

For specific usecases it is required for database confguration that the application shall be responsible for I&M data handling.
An API to enable I&M Handling in application shall be added. PNS_IF_SET_OEM_PARAMETERS_REQ shall be extended accordingly.
