edge-20.7.1

This edge release features the option to persist prometheus data to a volume
instead of memory, so that historical metrics are available when prometheus is
restarted. Additional changes are outlined in the bullet points below.

• Some commands like linkerd stat would fail if any control plane components
  were unhealthy, even when other replicas are healthy. The check conditions
  for these commands have been improved
• The helm chart can now configure persistent storage for Prometheus
  (thanks @naseemkullah!)
• The proxy log output format can now be configured to plain or json using
  the config.linkerd.io/proxy-log-format annotation or the
  global.proxy.logFormat value in the helm chart
  (thanks again @naseemkullah!)
• linkerd install --addon-config= now supports URLs in addition to local
  files
• The CNI Helm chart used the incorrect variable name to determine the createdBy
  version tag. This is now controlled by cniPluginVersion in the helm chart
• The proxy's default buffer size has been increased, which reduces latency when
  the proxy has many concurrent clients
