Prevent netifaces from introducing netmasks in the form of 'ffff::/16'.
Once this has been applied everywhere, all other fixes for this can be
dropped.

Currently computer netmask looks like 'ffff::/16' in slapos.xml.
With this commit, this netmask will be cleaned up to just 'ffff::'.

Computer definition file (slapformat-configuration.cfg) may now have:

```
[partition_0]
...
capability_list =
  fast-network
  more_disk_space
  yet another capability

...
```

Capabilities are line-separated and may otherwise contain whitespace.
Whitespace at the beginning and end of each line is stripped.

Previous code matched way too many files as belonging to the current
partition and wrongly removed them as obsolete: e.g. when processing
slappart1, all the configuration files belonging to slappart10 would
systematically be deleted, as if they belonged to slappart1 and were
now out-of-date. Same for all partitions starting with 'slappart1',
such as slappart11, slappart12, etc.

This resulted in all services in slappart1X being stopped and started
repeatedly and very often: stopped during processing of slappart1 and
started during processing of slappart1X, with potentially several
minutes of downtime, and a high percentage of downtime.

This is a fixup of db98a521.

This method is important we want to test it

  Since we are changing erp5_site_global_id, update cache is mantatory be called often

This could cause slapos request to hang forever while fetching the
json schema of an SR, and in particular it could cause buildout to
hang forever in instance processing when requesting a sub-instance.

   This constraint has no impact and you change your environment (ie.: use another memcache server) fix consistency will just break the system.

   This constaint also contains hardcoded values (which is already the setupped) so it dont make much sense keep this constraint around doing nothing.

   The user should be able to eventually change the cloudooo configuration after the setup it w/o change zope.conf.

   Just give some valid default if nothing is set, there is no reason to make things more complex them this, since the cloudooo_url is already setup on site creation.

  Rely on standard ERP5 implementation is enough

  Some values are set on testing environment, so no need to rely on IsLiveTest
