Add ADConnector compatibility

[francozulian]

We tried using SOCA and connecting it to an ADConnector type directory, but we needed to change find_existing_resources.py code in order for it to work. This was caused because of the attribute difference between the directory types (VpcSettings | ConnectSettings)

Also, not sure if related to the ADConnector per se, but we had an issue when getting the directory dns on install_soca.py, as it seems to get a string with a space inbetween ([ip, ip]), what causes it to break trying to only use the first part ("[ip,")

The workaround we used (it may not be the most appropriate), was checking the directory type before looking for it's attributes, and wrapping the dns data on a str() function

I'll look forwart to hear your comments

Thanks in advance

Hey @francozulian - Sorry for the super late reply. We are about to refresh SOCA with a new version soon. I would recommend to try with the updated codebase and see if this issue still persists
