Add MCUBoot and OTA over BLE with private key

[ekidsalan123]

Hi, 

I'm currently trying to add MCUBoot in my project.

The project was built successfully by adding these lines to prj.conf.

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

The memory report clearly indicates that MCUBoot has been successfully flashed onto my board.

I also can see DFU funtion and SMP service work in nrf connect APP.

Here are my questions:

1. How can I use a private key with currently settings?

2. How to update the firmware by using new nRF Connect SDK DFU? More precisely, what files should I prepare for?
