Speed OrangePi boot time

Is your feature request related to a problem? Please describe.
Trying to get vision booted as quickly as possible.

Describe the solution you'd like
Disable unneeded services that are shown by systemd-analyze to slow boot.
Disable network manager if static address set.

Describe alternatives you've considered
A short list:

• Disable the Bluetooth service. systemctl disable ap6275p-bluetooth
• Disable the cloud-init service. touch /etc/cloud/cloud-init.disabled
• Somehow get /etc/network/interfaces set correctly, and NetworkManager service disabled if a static address was requested.

...and changing the /etc/passwd entry for userid 'pi' to use bash instead of sh would be nice :)

Big fan of stuff booting faster yeah.

Wait, do we not kill Bluetooth and WiFi in our image yet? Yikes. We need to do that
