Upgrade hosted Ubuntu agents to 18.04 (#4431)

Replace some remaining references to Ubuntu 16.04 with 18.04. Note our release pipeline for docker images (`images-release.yaml`) calls `install.sh` with the `--package-arm` argument, which hasn't been updated for 18.04. That's a bigger effort that would need to be resolved before this can be merged (or handled in a separate PR).
