no need to have an exception here, long time ago bytes had an insecure
default, but we changed to make the default secure

When user ran out of inotify watch, starting wrappers using
wait-for-files is not possible:

This catches inotify errors and fallback to simple polling in that case.

Running logrotate -d on cluster with a lot of slaves results with execution
taking a lot of time (>10s, one some nodes ~20s), which leads to random
promise timeouts.

instance-slave-list.cfg.in is run by instance-frontend.cfg.in, which
implements that exact promise already.

Default software_type requests all required instances for the swarm.

Add getSpeed and getClimbRate to drone's API

Update FPS value to respect minimum sampling value of open62541 monitored items

Make sure to stop Pub/Sub server before stopping MavSDK thread

Now the default software-type request a list of drone software-type

keep old versions for python2

also sort versions and remove comments that make it hard to sort
versions and are not so helpful:
 - we can find the dependents of a package by looking in
  *eggs/*/EGG-INFO/requires.txt
 - nowadays, many python packages no longer have setup.py and wheels
  is becoming standard.

jsonschema egg now needs typingextension egg so we needed to pin it

In order to cleanup, I moved all eggs at once.

This reverts commit b3afa3fe.
