logon_script: check DNS resolution before proceeding

Browse Source 
If the IPA server FQDN cannot be resolved at startup (e.g. due to a
DNSSEC outage or network not yet ready), the logon script would silently
fail later. The new check prompts the user to retry, continue anyway, or
quit, so the problem is immediately visible.
