For now Payzen and Wechat

Depending on the netifaces version the netmask can come with or without
lenght prefix, so support both cases and consider netmask with prefix
as equal to without prefix.

The only result will be update of the netmask in the computer XML file.

self.interface.getGlobalScopeAddressList which uses netifaces can have
different sorting of the addresses depending of the version, so prefer the
already configured IPv6 address.

According to this [code](https://lab.nexedi.com/nexedi/slapos.core/blob/master/master/bt5/slapos_jio/PathTemplateItem/web_page_module/rjs_gadget_erp5_page_slap_computer_view_js.js#L127) . I believe the test `testSlapOSJSServer` currently failed due to a typo. There may have other failing in this test, but at least we can fix this one first.

This isn't the most suitable script for this anymore or some extra configurations can be used.

In Gitlab,  if URL is like https://USERNAME:PASSWORD@somedomain.com then gitlab will return 401 and ask for basic Authentication.

For this kind of URL, we simply extract username and password and send ajax request with Basic Auth.

follow up of f2798c25

it was still crashing when "create_tap = True"

add erp5_accounting to fix the following:
runTestSuite: Adding erp5_configurator business template ... (imported in 1.134s) (missing dependencies : ['erp5_accounting']) done (5.681s)

add a test to see if all BT are correctly installed

Also renames it so it reflects well its function.

Before the fix in 77c4cca0, each call
to /loadComputerConfigurationFromXML was deleting all the partition in
the database. After the fix, because the test environment is not cleaned
correctly between different tests, some slapparts would remain between
following tests.
Thanks to this commit, the previous behavior is restaured.

loadComputerConfigurationFromXML must be idempotent : if partitions are requested the
same, then nothing should be done.
With this commit, we make sure we only delete partitions that don't exist anymore,
create new ones, and update the remaining ones

* --token ask in "slapos configure client" is not supported ("ask" is interpreted
     as the argument value, iow the token)
   * node_name : a node name is an unknown concept. On slapos.vifib.com interface, the
     nodes have titles and references
