Allow add action in iis_config_property to support multiple properties

[jeffreycoe]

Description

The iis_config_property resource does not currently support values which require more than one property. For example, the following command would not be supported currently since the value parameter has a hash which contains multiple keys:

Add-WebConfigurationProperty -PSPath 'MACHINE/WEBROOT/APPHOST' -Location "Default FTP Site" -Filter "/system.ftpServer/security/authorization" -Name "." -Value @{accessType='Allow';users='ftp_user';permissions='Read, Write'}

This PR would update the add action for the iis_config_property resource and allow the value property to use Hash values to support multiple properties.

The property custom resource property would be ignored if passing in a Hash to the value property.

Below are examples of how the custom resource would be used with multiple properties vs a single property:

iis_config_property 'add_http_trace_method' do
  ps_path 'MACHINE/WEBROOT/APPHOST'
  filter 'system.webServer/security/requestFiltering/verbs'
  value(
    verb: 'TRACE',
    allowed: 'False'
  )
  action :add
end

iis_config_property 'configure_iis_test_new_index_default_document' do
  ps_path 'MACHINE/WEBROOT/APPHOST'
  filter '/system.webServer/defaultDocument/files'
  property 'value'
  value 'new-index.html'
  action :add
end

Looking for feedback and suggestions on this implementation. Thanks!
