More native support like RaspberryPi image

[srbala]

AlmaLinux RaspberryPi image should more native support which are available in standard RaspberryPi. Following are good to have in consideration to native support ...

• [ ] Configure WiFi on first time boot using config network-data file from boot partition
• [ ] Create new using user-data config file, create new user on first boot
• [ ] Configure user SSH settings based on ssh config entry
• [ ] Expand root partition (running rootfs-expand command
• [ ] Make config.txt file updated based on user prompt - screen rescan required etc

Sample config file created by Raspberry Pi imager below

Wifi config

# File network-config
version: 2
wifis:
  renderer: networkd
  wlan0:
    dhcp4: true
    optional: true
    access-points:
      "MyWiFi-NETWORK_SSID":
# MyWiFi-NETWORK_SSID password hash      
        password: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

User config

# File user-data
#cloud-config
hostname: raspberrypi-alma
manage_etc_hosts: true
packages:
- avahi-daemon

    };

I'm working on this now.

network-config won't work due to this bug until updated to 22.2 or later. https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1906187

Other stuff are working fine on my development working tree.
