Make show interfaces container aware. This is done by looking though
all podman containers for interfaces and looking up there info from
network namespaces on the main system / hypervisor.
Interfaces controlled by containers are clearly marked in the "show
interfaces" output, with a single gray row. Telling the user that they
belong to one or more named containers. The user can then run "show
interface name NAME" on interfaces owned by containers, which provided
some additional info, such as mac address and stat counters.
The patch also add support for printing veth peers which are owned by
containers.
Lastly, the patch also adds test cases for this functionality.

In this patch we add some arbitrary system output files which contains
interface data. Such as the output from "ip link" and "ethtool". These
files are used by yanger instead of running the actual commands.
Yanger then generates a lot of YANG json data, which are merged using
jq into something that looks like the sysrepo operational data on
a running system. This data is then passed though cli-pretty and its
ouput is compared to the static expected output in the .txt files in
cli-output.
Here's a basic flow overview.
* system-output/foo.json -> yanger ->> data
* system-output/bar.json -> yanger ->> data
* data -> merge -> sysrepo-operational-data
* sysrepo-operational-data -> cli-pretty -> output.txt
* compare output.txt too cli-output/show-foobar.txt
The result of this is that if something changes in yanger OR in
cli-pretty. The corresponding system-output file needs to be updated
for the test to pass. This is indented to catch regression where the
output is unintentionally changed.
