Install and configure Ubuntu nodes with Nvidia drivers and NiceDCV (#3728)

These scripts will configure build and test Ubuntu 18/20 nodes with:

Nvidia gaming drivers for GPU instances (g4dn)
lightdm for Ubuntu 18 and gdm3 for Ubuntu 20 (wayland is disabled here, but should have xcb capabilities)
NiceDCV for remote console access

Note: Does not include user setup and firewall configurations
