This means the user gave up, so we cancel so the new payment is created or Subscription Request is cancelled.

On some test machines, we saw test failures because openssl version mismatch:

What we see in this traceback is that the version of openssl used was the one from system ( in `/usr/lib/` ), which should not happen because we are using setting rpath to slapos libraries. We had a test checking for missing rpath that could not resolved, but our test did not catch missing rpath that can be resolved on a system library, which is also wrong because this system library might be a different version like here or even be missing.

Except a short whitelist of system libraries, we should have always set
rpath so that the slapos version of the library is used.

We had issues with components which where compiled with slapos version
of openssl but linked without rpath. At runtime they were using system
openssl.

Rewrite our complex grep shell pipeline in python, with a function
parsing ldd output so that we can check not only for not found dynamic
libraries, but also for libraries that are found outside of slapos
library dirs.

This also fixes problems that this grep pipeline did not support paths
with spaces in their names.

Each time slave partition changes (it is added or updated) the master
partition timestamp has to be recalculated.

Fix long lines, incorrect type annotations and adjust a bit to make mypy
happy.

Sometimes instanciation fail because some service do not start and the
"check port listening" promises fail. In this case, it's very important
to also have the partition content to see what's in the log files.

the pagination doesn't work because
SoftwareInstance_getConnectionParameterList returns always all

Implementing improvements discussed in nexedi/slapos@1a5df533 (comment 93275) and on  nexedi/slapos.core!150 (comment 92471) 

We now only store slapos logs one per `setUpModule` for software and `setupClass` for instances.

There's no de-duplication, but it's still a bit big.

Include additional states to handle additional steps when handle a subscription requests.

started: Once Subscription is started, it means that instance is ready and user was notified
stopped: Once Subscription is stopped, it means that instance is destroyed but not all invoices were payed. Subscription is about to be Delivered (Closed).

This prevents things get broken.

Once the Computer/Hosting Subscription is transferred using Internal Packing List, the associated installation and instance should acquire security from the respective context.
