generate ConfigurationFile.ini dynamically from attributes

Handle configuration file creation dynamically from attributes:

./templates/default/ConfigurationFile.ini:

<% @properties.each_pair do |key, value| -%>
  <% if value.is_a? Array -%>
<%= key %>=<%= value.map { |item| %("#{item}") }.join(' ') %>
  <% else -%>
<%= key %>="<%= value %>"
  <% end -%>
<% end -%>

example environment json:

{
  "sql_server": {
    "install": {
      "properties": {
        "key1": "value1",
        "key2": "value2",
        "array": ["item1", "item2", "item3"]
      }
    }
  }
}

end result:

key1="value1"
key2="value2"
array="item1" "item2" "item3"

This way the comments are lost, but also that can be attached if really necessary

Start with ./templates/default/ConfigurationFile.ini and compare its current rendering with the example environment JSON in the issue. Verify how @properties is supplied, then confirm that scalar attributes render quoted and arrays render as space-separated quoted items, with the shown output as the completion criterion.
