There should be no functional change in this patch.
In this patch we rewrite the data collection in python3. This is the
new script called "yanger". It runs various commands on the system,
such as "ip" and "ethtool". It then mangles the output data from these
commands into valid YANG data.
The yanger script is started from the sysrepo callback in the statd c
code. Its output is parsed using lyd_parse_data_fd().
This means that the daemon part of statd is still written in c and the
new python code is only used when getting a query callback from
sysrepo. The c code still handles the interface netlink messages from
the kernel which controls what interfaces statd should do sysrepo
subscribe/unsubscribe to.

This patch adds the framework for reading ethtool statistics and
inserting it into the operational datastore.
The ethtool data we rely on is "group data" such as "eth-mac" or
"rmon".
This data can be displayed using:
ethtool --json -S e0 --all-groups
The "group data" is still missing for most common drivers, so testing
this will require a firmware which has support for it.
