init_xml and update_xml deprcated parameters, use for new modules data instead.

• init_xml - list of XML files with data that will load to DB at moment when you install module.
• update_xml - list of XML files with data that will load to DB at moment when you install or update module.

• data - list of XML, CSV or YAML files with data that will load to DB at moment when you install or update module. XML data file can have as install data and update data. It control by attribute noupdate of tag data.

  <openerp>
      <data>
          {install and update}
      </data>
      <data noupdate="1">
          {only install}
      </data>
  </openerp>
  

I would like to add that `noupdate="1"` doesn't mean that it will not load on upgrading the module.

If you add a new `record` inside a `data` with `noupdate="1"` it will get loaded. At least in version 12.
