Prevent serving TLS via ports.grpc
We remove the ability to run the ports.grpc in TLS mode to avoid
confusion and to simplify configuration. This breaking change
ensures that any user currently using ports.grpc in an encrypted
mode will receive an error message indicating that ports.grpc_tls
must be explicitly used.
The suggested action for these users is to simply swap their ports.grpc
to ports.grpc_tls in the configuration file. If both ports are defined,
or if the user has not configured TLS for grpc, then the error message
will not be printed.
In 1.13.2 we added a new flag called use_auto_cert to address issues
previously documented in the upgrade guide. Originally there was no way
to disable TLS for gRPC when auto-encrypt was in use, because TLS was
enabled for gRPC due to the presence of auto-encrypt certs.
As of 1.13.2, using auto-encrypt certs as the signal to enable TLS for
gRPC is opt-in only. Meaning that if anyone who had upgraded to 1.13
relied on that side-effect, they now need to explicitly configure it.

Adds guidance when upgrading a Consul service mesh deployment to 1.13 and:
- using auto-encrypt or auto-config; or
- the HTTPS port is not enabled on Consul agents
Ensure that the peer stream replication rpc can successfully be used with TLS activated.
Also:
- If key material is configured for the gRPC port but HTTPS is not
enabled now TLS will still be activated for the gRPC port.
- peerstream replication stream opened by the establishing-side will now
ignore grpc.WithBlock so that TLS errors will bubble up instead of
being awkwardly delayed or suppressed
Due to build changes in Consul 1.12.0 the `+ent` modifier is missing
from the version reported by `/v1/agent/self`.
Nomad looks for the `ent` modifier when determining whether to reconcile
services in non-default namespaces. Without the modifier Nomad will only
end up removing services from the default Consul namespace.
* Use CodeTabs for examples in multiple formats.
* Ensure correct language on code fences.
* Use CodeBlockConfig for examples with filenames, or which need
highlighted content.
