system tests: new tests

- podman network create: new test

- podman pull by-sha + podman images -a (#7651)

- podman image mount: new test

- podman pod: --infra-image and --infra-command (#7167)

For convenience and robustness, build a new testimage
containing a custom file /home/podman/testimage-id
with contents YYYYMMDD (same as image tag). The
image-mount test checks that this file exists and
has the desired content. New testimage also includes
a dummy 'pause' executable, for testing pod infra.

Updates from testimage:20200902 to :20200917
