These changes are intended to make yanger a bit more robust. Instead of
bailing out on command errors, we now return empty string or object back
to the callee in run_cmd() and run_json_cmd().
One example where yanger previously exited hard, and dragged with it the
entire session, is when inspecting container status or when attempting
to restart container instances which have yet to be created/stopped.

Switch to logger, with syslog backend, instead of print() for logging
errors. This way we can log errors/warnings yet still return partial
JSON data back to statd. For example, failing to read JSON counters
from ethtool should not break "show interfaces", just return empty
array and log failure to run command.

- Missing whitespace in assignments, before comments and methods
- Drop semicolons from end of statements
- Use 'if foo not in bar' instead of 'if not foo in bar'
- Some too long lines (not all, that would be painful)

On boards like the R2S and the VisionFive2 `ethtool --json -S ethX` is
not yet supported. This patch allows ethtool to fail, with a slightly
better log message, without breaking the operational datastore.

Actually a part of statd, but had to make
a separarate package to get it to work.
Statd helper-scripts are now pre-compiled instead of doing it
in runtime.
