@zbindenren @djboris9 what do you think ? the effect on the number of open file descriptor/goroutines is really interesting. the http request duration also starts to be more interesting ! do you agree that this mode should be the default ?

@clementnuss LGTM 👍 |
the default configuration changes: now kubenurse will NOT reuse connections per default. this permits to have a clearer picture, as closed long-lived connections might not involve DNS resolution, and might hide Load balancer pool problems.

This will be a minor change, as the results and behaviour of Kubenurse is modified consequently.
