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

    OSError: [Errno 28] No space left on device

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.

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.

This change unexpectedly impacted ERP5 deployment.

ZEO 5.4.0 fixes several concurrency bugs and provides other
improvements. See changelog in https://pypi.org/project/ZEO/5.4.0/
for details.

Going from ZODB 5.6.0 to 5.8.0:

- removes leftovers of pre-MVCC read conflicts,
- relaxes assertion in tests that relate to NEO,
- brings up interface requirements in line with Wendelin.core 2 and WCFS,
- optimizes IO in fsrefs,
- fixes fsdump to match fsstats,
- provides new tests that exercise potential concurrency issues in
  storage implementations more thoroughly,
- provides other fixes and improvements.

Please see https://github.com/zopefoundation/ZODB/compare/5.6.0...5.8.0 and
https://pypi.org/project/ZODB/5.8.0/ for details.

Database password is now randomly generated.
Now test that the pre-filled password matches the mariadb url.

By inspecting current configuration stored in .data-disk-amount of the
partition configuration directory extend the conflict protection to really
observed configurations.

Adapt the README to follow real messages and explain a bit more the situation.

Patch nexedi/slapos@15e26abd explicitly declared
go version 1.17 for the 'helloworld' SR.

This was done at a time when we already had [golang1.17] in component/golang,
but the default was still go1.16. The explicit declaration allowed the 'helloworld' SR
to already switch to the newest go version.

Since patch nexedi/slapos@d32524c3
we use go1.18 as our default version. In order to allow 'helloworld' to use our newest
SlapOS supported go version, it's therefore sufficient nowadays to simply remove the
explicit declaration.
