Daniel unbrot Pätzold 8e2cd35eb4 logon_script: check DNS resolution before proceeding
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.

# A. If "sudo -l" wants a password (some installations!):
# If a matching rule with !authenticate is found, no passwd will be asked and retno is 0
# If there is a rule matching with no !authenticate, then a password would be asked. This is prevented, so there will only be the
# error "a password is needed" an retno is 1
# If there is no sudo rule at all, it will only set retno to 1
#-> Anyway, returning > 0 means the user is not allowed to run sw installation, which is fine. Print Message and skip installation.
#
# B. If "sudo -l" doesn't not want a password, then
# RETNO = 0 , but the Output of "sudo -l -l" must als be checked, if there is an Option !authenticate in the returnung string, otherwise a failed installation cannot be
# divided from a missing sudo-rule
