Use by default checkUserCanChangePassword, but as in ERP5 users do not have
such persmission to Person document which defines them, check if logged in user
login is same as document reference.

Prove that user can request and revoke certificate for himself.
Prove that user cannot request twice the certificate.
Prove that user cannot request nor revoke certificate for another one.

Note: Currently failing, because users cannot set own passwords.

It allows to get/revoke certificates for Person. Protected in same way as setting Person's password.

This is too dangerous, as it allows to generate certificates for any user.

Try to confirm order related to another requested software instance. It shall
fail with ValueError, which indicates in Vifib, that no free partition was
found, which means that SLA was correctly used.

As there is no way to have returned object, generate random value and reuse it
later to fetch exact object.

Also extended tests with Order Line checks.

sla_xml have to be passed always. As this test have to work on low level API
it is required to follow such API.

It supports cases when Person is in middle of requesting of Software
Instance.

User cannot fetch his instance until related sale order is not confirmed.

brctl is the only command which remains mandatory (except if alter_network
is false), as it is used to fetch information from system that even an
unprivileged user can see.

Example use:
PATH=$PATH:/usr/sbin ./bin/slapformat -cdv slapos.cfg

Prepares for incomming monkey-patching.

Output system commands and system-altering functions from python's os
module.

SLA XML is stored on Software Instance, but in many place the dictionary have
to be used.

It will be later used to follow SLA.
