freddygv a21e5799f7 Use internal server certificate for peering TLS
A previous commit introduced an internally-managed server certificate
to use for peering-related purposes.

Now the peering token has been updated to match that behavior:
- The server name matches the structure of the server cert
- The CA PEMs correspond to the Connect CA

Note that if Conect is disabled, and by extension the Connect CA, we
fall back to the previous behavior of returning the manually configured
certs and local server SNI.

Several tests were updated to use the gRPC TLS port since they enable
Connect by default. This means that the peering token will embed the
Connect CA, and the dialer will expect a TLS listener.

Consul Testing Utilities

This package provides some generic helpers to facilitate testing in Consul.

TestServer

TestServer is a harness for managing Consul agents and initializing them with test data. Using it, you can form test clusters, create services, add health checks, manipulate the K/V store, etc. This test harness is completely decoupled from Consul's core and API client, meaning it can be easily imported and used in external unit tests for various applications. It works by invoking the Consul CLI, which means it is a requirement to have Consul installed in the $PATH.

Following is an example usage:

package my_program

import (
	"testing"

	"github.com/hashicorp/consul/consul/structs"
	"github.com/hashicorp/consul/sdk/testutil"
)

func TestFoo_bar(t *testing.T) {
	// Create a test Consul server
	srv1, err := testutil.NewTestServerConfigT(t, nil)
	if err != nil {
		t.Fatal(err)
	}
	defer srv1.Stop()

	// Create a secondary server, passing in configuration
	// to avoid bootstrapping as we are forming a cluster.
	srv2, err := testutil.NewTestServerConfigT(t, func(c *testutil.TestServerConfig) {
		c.Bootstrap = false
	})
	if err != nil {
		t.Fatal(err)
	}
	defer srv2.Stop()

	// Join the servers together
	srv1.JoinLAN(t, srv2.LANAddr)

	// Create a test key/value pair
	srv1.SetKV(t, "foo", []byte("bar"))

	// Create lots of test key/value pairs
	srv1.PopulateKV(t, map[string][]byte{
		"bar": []byte("123"),
		"baz": []byte("456"),
	})

	// Create a service
	srv1.AddService(t, "redis", structs.HealthPassing, []string{"primary"})

	// Create a service that will be accessed in target source code
	srv1.AddAccessibleService("redis", structs.HealthPassing, "127.0.0.1", 6379, []string{"primary"})

	// Create a service check
	srv1.AddCheck(t, "service:redis", "redis", structs.HealthPassing)

	// Create a node check
	srv1.AddCheck(t, "mem", "", structs.HealthCritical)

	// The HTTPAddr field contains the address of the Consul
	// API on the new test server instance.
	println(srv1.HTTPAddr)

	// All functions also have a wrapper method to limit the passing of "t"
	wrap := srv1.Wrap(t)
	wrap.SetKV("foo", []byte("bar"))
}
