Description
Currently, when doing a filter chain match on server names you cannot use a partial wildcard:
From a very quick look at how the server names are looked up:
https://github.com/envoyproxy/envoy/blob/master/source/server/filter_chain_manager_impl.cc#L418
it seems like supporting this could be done without a huge perf impact.
We have a use case for this, which would allow us to split a bunch of vhost/route configs into their own chains. This would save us from having to support per route overrides for the filters that need to be globally disabled and only enabled for some vhosts/routes.
Any reasons not to support this? Thoughts?
