Description

Due to #2870 the dhcp_native_ms provider always tries to set the
PXEClient opt to empty. However this does not exist in all DHCP servers
(tested on 2008R2) and in this case we currently fail with:

INFO -- : Added DHCP reservation for foo.example.com(10.0.2.20 / 52:54:00:84:64:03)
    DEBUG -- : key: "PXEClient" 
    DEBUG -- : executing: c:\windows\system32\cmd.exe /c c:\Windows\System32\netsh.exe c dhcp server 127.0.0.1 scope 10.0.0.0 set reservedoptionvalue 10.0.2.20 60 String "" 
    INFO - : Vendor class not found
    ERROR -- : Netsh failed:

so ignore errors to set that option.

fixes #13575 - Don't fail on missing PXEClient dhcp opt

Due to #2870 the dhcp_native_ms provider always tries to set the
PXEClient opt to empty. However this does not exist in all DHCP servers
(tested on 2008R2) and in this case we currently fail with:

INFO -- : Added DHCP reservation for foo.example.com(10.0.2.20 / 52:54:00:84:64:03)
     DEBUG -- : key: "PXEClient" 
     DEBUG -- : executing: c:\windows\system32\cmd.exe /c c:\Windows\System32\netsh.exe c dhcp server 127.0.0.1 scope 10.0.0.0 set reservedoptionvalue 10.0.2.20 60 String "" 
     INFO - : Vendor class not found

    C:/Users/Administrator/Downloads/smart-proxy/vendor/ruby/2.1.0/gems/sinatra-1.4.7/lib/sinatra/base.rb:1611:in `call'

so ignore errors to set that option.

Also add a test that verifies adding dhcp records and one that checks
that we still correctly raise errors when we fail to set dhcp options
(execpt for PXEClient).
