* Also store shared instance list after retrieving it

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

This parameter no longer exists, this was not removed correctly

"repozo --verify" is not working as this code expects it to: it simply
prints errors in stdout, and doesn't return an error code in case of
error. Thus, running it had absolutely no effect, except wasting IO
and CPU time.

This commit introduces the use of "repozo --recover --with-verify",
which runs the verify and the recover in a same step, and has the
advantage to raise (it doesn't exit with 0) in case of error. Also, as
it does the verification and the recovery at the same time, it uses
half the IO for the read. On a production server using SSDs, with a
ZODB of 1Tb, runner-import-restore now takes 14h instead of 26h, iow a
performance increase of 46%.
