Change default timeouts to 1s and add possibility to configure them

Christopher Bockrequested to merge
cb/auto-apt-proxy:timeout into master
  • Set default timeout for resolving with getent and proxy checks via apt-helper to 1 second as the original 5 seconds easily adds up to more than 30 seconds to detect our proxy in networks where the _gateway doesn't reject packets and the SRV entry is in use. (Closes: #1108265)
  • Add new apt.conf configuration settings
    • AutoAptProxy::Timeout::DNS="1" for getent lookups
    • AutoAptProxy::Timeout::Proxy="1" for apt-helper proxy tests
    • AutoAptProxy::Debug="" to enable debugging permanently
    • AutoAptProxy::Cache"60" to allow different values than 60s caching

Thoughts?
