Compiling this will set an optional SNI field on each DiscoveryTarget.
When set this value should be used for TLS connections to the instances
of the target. If not set the default should be used.
Setting ExternalSNI will disable mesh gateway use for that target. It also
disables several service-resolver features that do not make sense for an
external service.
If the entry is updated for reasons other than protocol it is surprising
that the value is explicitly persisted as 'tcp' rather than leaving it
empty and letting it fall back dynamically on the proxy-defaults value.
* website: update the vs. envoy and proxies page
This is the second result on Google for "consul envoy" and
it seemed like it needed a bit of an upgrade to help clarify the
current state.

Since generated envoy clusters all are named using (mostly) SNI syntax
we can have envoy read the various fields out of that structure and emit
it as stats labels to the various telemetry backends.
I changed the delimiter for the 'customization hash' from ':' to '~'
because ':' is always reencoded by envoy as '_' when generating metrics
keys.
Add parameter local-only to operator keyring list requests to force queries to only hit local servers (no WAN traffic).
HTTP API: GET /operator/keyring?local-only=true
CLI: consul keyring -list --local-only
Sending the local-only flag with any non-GET/list request will result in an error.
The json decoder inside of the HCLv1 hcl.Decode function behaves
unexpectedly when decoding generically into a map[string]interface{} as
is done for 'consul config write' pre-submit decoding.
This results in some subtle (service-router Match and Destinations being
separated) and some not so subtle (service-resolver subsets and failover
panic if multiple subsets are referenced) bugs when subsequently passed
through mapstructure to finish decoding.
Given that HCLv1 is basically frozen and the HCL part of it is fine
instead of trying to figure out what the underlying bug is in the json
decoder for our purposes just sniff the byte slice and selectively use
the stdlib json decoder for JSON and hcl decoder for HCL.
