add workflow method to request one slave instance. The script added is a blank script; only to commit a skel of Slave Instance

remove form used to list the Slave Partitions. This form is not used anymore because Slave Partition is obsolete

- Added portal type Slave Instance;
- Created SlaveInstance_view without ssl_key and ssl_certificate
- Created slave_instance_slap_interface_workflow and associated it to Slave Instance

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.
