Added podman scripts

[Victoremepunto]

This is still a WIP

Provides Podman based bash scripts and pod.yaml template to deploy locally the Ingress service stack using podman.

Thanks for the initiative, @Victoremepunto! A couple comments so far inline.

Suggested change

	$RUNNER network inspect $PODMAN_NETWORK &>/dev/null || $RUNNER network create $PODMAN_NETWORK

[akofink]

I think it'd be useful (to me, at least) to have a $RUNNER env variable, defaulted to podman:

Suggested change

	RUNNER=${RUNNER:podman}

Then, for example, you can invoke the script like this:

RUNNER='sudo podman' ./scripts/podman-bootstrap.sh

How have you been running it? With sudo ./scripts/podman-bootstrap.sh ?

yeh exactly, as this version needs to manipulate networks and at the moment podman requires sudo privileges for it. not sure I want to keep it that way, but one of the things we will be dropping if going for rootless podman containers is dns domain name resolution. the alternative in rootless podman would be to keep all services inside the same pod, and listen to localhost:{service-port} when communicating with other containers.

Take a look at the shellcheck output on these scripts. There are a few suggestions worth fixing.
