Yeah after adding pprof Boris looked into it and figured that we might cause a leak with stale connections, leader required to prevent race conditions on clean-up only, it won't affect any other path

I imagined the bridge being stateless. now it has "state" of a connection?
I even imagined it with HPA in the future to support spikes😆

Bad choice of words, but bridge, as stateless as it is, has a configmap of actors. Before pprof the list was stable. After pprof was added bridge got registrations from specific pods which made the configmap grow and keep stale actors on the list. So we need to clean the dead actors somehow.
On the bridge side I added a cleaner that does the job but since multiple bridges can run at the same time I needed an election to prevent multiple cleaner workers.

I bet we'll reach HPA too :P
