Extending the VM initialization

[engelmi]

Please describe what you would like to see

It would be great to have a complete set of functions to set all options in the VM initialization struct. Currently, only the custom-script and hostname are supported (and NicConfigurations will be partially added in #249).
A complete list of fields can be found in the documentation for oVirts REST API in the Initialization struct section.

Checklist for parameters

• active_directory_ou
• authorized_ssh_keys
• cloud_init
• cloud_init_network_protocol
• configuration
• dns_search
• dns_servers
• domain
• input_locale
• org_name
• regenerate_ids
• regenerate_ssh_keys
• root_password
• system_locale
• timezone
• ui_language
• user_locale
• user_name
• windows_license_key

Please describe the solution you'd like

All additional parameters should optional and only be configurable via builder:

initialization := NewInitialization("custom-script", "hostname").WithSomeParam("some-param");

Hi
@engelmi , I added boolean and string fields in vm.Initialization structure #253

I am thinking about cloud_init and cloud_init_network_protocol.

According https://www.ovirt.org/documentation/doc-REST_API_Guide/#types-initialization - this fields deprecated and maybe we should not implement this.

Implementation for vm.initialization.configuration.data field is complex for me. I try to make test for it and send some xml to ovirt (like in https://www.ovirt.org/documentation/doc-REST_API_Guide/#types-configuration example), but always i have (409) bad request. So i have no idea how to check this field.
