Changes
skipper: add server connection keepalive limits (#3246)
Clients may connect to a subset of Skipper fleet which leads to uneven
request distribution and increased cpu usage.
Autoscaling of Skipper fleet is not effective because clients stay
connected to old instances while new instances are underutilized.
This change adds ConnManager that tracks creation of new connections
and closes connections when their age or number of requests served
reaches configured limits.

filters/auth: release tokeninfo cache mutex earlier (#3241)

predicates/host: add HostAny benchmark (#3239)
Current implementation uses linear probe that works well for small number
of hosts.
I thought about implementing it using map lookup but that is slower for
less than 50 hosts so I propose to only keep the benchmark that may be used
for future improvements.
Here is comparison with map-based implementation for reference:
