Stable 2.3.1 Release Notes (#2869) 

This stable release adds a number of proxy stability improvements.

To install this release, run: `curl https://run.linkerd.io/install | sh`

**Special thanks to**: @zaharidichev and @11Takanori!

**Full release notes**:

* Proxy
  * Changed the proxy's routing behavior so that, when the control plane
    does not resolve a destination, the proxy forwards the request with minimal
    additional routing logic
  * Fixed a bug in the proxy's HPACK codec that could cause requests with
    very large header values to hang indefinitely
  * Replaced the fixed reconnect backoff with an exponential one (thanks,
    @zaharidichev!)
  * Fixed an issue where requests could be held indefinitely by the load balancer
  * Added a dispatch timeout that limits the amount of time a request can be
    buffered in the proxy
  * Removed the limit on the number of concurrently active service discovery
    queries to the destination service
  * Fixed an epoll notification issue that could cause excessive CPU usage
  * Added the ability to disable tap by setting an env var (thanks,
    @zaharidichev!)
