Skip missing certificate warning in RDP for MacOS

Hello,

in Windows you can disable warnings concerning  missing certificate upon starting a RDP session, however on the MacOS version this is not possible, but quite annoying when frequently using RDP.

Could it be possible to add this feature?

Expected behaviour:

1. On first connection missing a certificate, issue a warning as usual:
   
2. Add an option to ignore future warnings (as for the Windows counterpart)
3. On subsequent connections, if the ignore option was selected by user, skip the dialog

Thanks!
