For now the only exception is slapos_configurator only

While running tests using all.bash, `$HOME/.cache/go-build/` is
populated with data referencing the build folder. This is problematic
when using shared parts and installing a not pinned software release
multiple times, like it is the case on test node.

A scenario like this can happen:

 - a first succesful build install in `<shared>/golang1.21/<HASH1>`
 - golang1.21 section is changed in a the software release
 - golang1.21 is installed in `<shared>/golang1.21/<HASH2>`, running
   test fails because the cache `<software_folder>/.cache/go-build/` in
   references paths from `<shared>/golang1.21/<HASH1>/.build/go/src`,
   that was used when building the first build and have been removed
   while installing.

This is visible with errors like this:

This reverts commit 5814aadb.

Grrr Jinja2 does not want me to write:

{%-   if any(node.get(x, 1) for x in ('admin', 'master', 'storage-count')) %}

See https://docs.python.org/3/using/cmdline.html#envvar-PYTHONHASHSEED

Setting a value will set the environment variable for all zope processes
and for the test runner.

Default behavior is:
  - for zope: do not set the variable, so default python behavior will
  be used ( equivalent to setting `0` on python2 and `random` on python3)
  - for test runner: generate a random value for each execution and
  print it, to make it easy to re-run a failing test with the same seed.

This means that ERP5 tests will likely reveal problems where code
depends on python2 behavior of deterministic hashing. To keep previous
behavior (and hide these problems), it's possible to set
python-hash-seed to 0 in test suite parameters.

The CertificateAuthority tool in ERP5 uses UTF8 encoding for certificates,
but by default OpenSSL does not. This cause an error when using non-ascii
characters:

```
The localityName field is different between CA certificate and the request
```

To solve the problem, the Certificate Authority recipe should use the same
encoding as ERP5, which requires adding `-utf8` option when invoking
OpenSSL.

For instance, creating a certificate with `localityName` Москва
will give the following with the default OpenSSL encoding:
`\C3\90\C2\9C\C3\90\C2\BE\C3\91\C2\81\C3\90\C2\BA\C3\90\C2\B2\C3\90\C2\B0`.

UTF8-encoding this same string gives `\D0\9C\D0\BE\D1\81\D0\BA\D0\B2\D0\B0`,
which is what ERP5 expects.

This option will give fixed IP to each SIM card.

component/mavsdk: v↑ mavsdk (0.39.0 -> 1.4.13)
component/gwsocket: add gwsocket websocket server

software/js-drone: use WebSocket for subscriber
slapos/software: run quickjs as a service

 * the default is already tested so drop TestRe6stVerificationUrlDefaultSlave
 * use locally provided URL to check re6st-verification-url, to not depend
   on external resources

slapos!1501 did a good job with making default disabled, but during the code
review tests changes were not well checked.

logrotate test for the rapid-cdn SR have been failing for quite some
time because of a squid.log file created (and henceforth rotated) on
any slave instance of the CDN:

```
Traceback (most recent call last):
    self.assertEqual(
AssertionError: Items in the second set but not the first:
'squid.log_10.0.160.212.20240306.23h57m09s-20240307.00h00m02s.old.xz'
```

Since we do not want to test this file in that specific test, this
commit instead loosely check the content of the rotated files
directory.
In other words, the test now checks for the presence of the two
files to be tested, but avoid failing if other files exist.

This goes in line with the two following lines of that same test,
loosely checking for file absence instead of an empty directory.

OPENSSL's libraries in this case SlapOS ones.

The SR didn't compile without libssl-dev package. Correctly use the
openssl lib from slapos.

Every restricted python code on python2 will be compiled as if it had
`from __future__ import print_function`, to ease transition away from
python2.

To update project code, 2to3 from python2.7 seems to do a good job.
Invoking like from the root of a repository rewrite all scripts:

    2to3  --write --nobackups --no-diffs --fix=print .

When the backend to redirect to uses scheme standard port it's cleaner to
redirect to URL without the port.

See https://www.rfc-editor.org/rfc/rfc9110.html#name-https-normalization-and-com:

"If the port is equal to the default port for a scheme, the normal form is to
omit the port subcomponent."

I forgot to update hashes after commits b6959875 and 7906b01c.
This commit solves the problem by updating slapos-master hashes.

I used the following commands:
autopep8 test_ors.py --select=E101 --ignore=E121 --indent-size=2 --in-place
autopep8 test.py --select=E101 --ignore=E121 --indent-size=2 --in-place
