stable-2.13.6

This stable release fixes a regression introduced in stable-2.13.0 which
resulted in proxies shedding load too aggressively while under moderate
request load to a single service ([#11055]). In addition, it updates the
base image for the `linkerd-cni` initcontainer to resolve a CVE in
`libdb` ([#11196]), fixes a race condition in the Destination controller
that could cause it to crash ([#11163]), as well as fixing a number of
other issues.

* Control Plane
  * Fixed a race condition in the destination controller that could
    cause it to panic ([#11169]; fixes [#11193])
  * Improved the granularity of logging levels in the control plane
    ([#11147])

* Proxy
  * Changed the default HTTP request queue capacities for the inbound
    and outbound proxies back to 10,000 requests ([#11198]; fixes
    [#11055])

* CLI
  * Updated extension CLI commands to prefer the `--registry` flag over
    the `LINKERD_DOCKER_REGISTRY` environment variable, making the
    precedence more consistent (thanks @harsh020!) (see [#11144])

* CNI
  * Updated `linkerd-cni` base image to resolve [CVE-2019-8457] in
    `libdb` ([#11196])
  * Changed the CNI plugin installer to always run in 'chained' mode;
    the plugin will now wait until another CNI plugin is installed
    before appending its configuration ([#10849])
  * Removed `hostNetwork: true` from linkerd-cni Helm chart templates
    ([#11158]; fixes [#11141]) (thanks @abhijeetgauravm!)

* Multicluster
  * Fixed the `linkerd multicluster check` command failing in the
    presence of lots of mirrored services ([#10764])
