fix(base) reduce the amount of timers used #105

Closed kikito closed 3 years ago

kikito commented 4 years ago

This PR changes the timers so that instead of creating one per balancer we crete a single global one. The price payed is that we must store a glocal variable with all the lbs inside.

The DNS refresh is async so no further timers/threads are needed.

Note that the single global recurring timer is now marked as "detached" so that it is not garbage-collected.
