* agent: add failures_before_warning setting
The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.
The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.
When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

It can only work if there is a running service instance in the local DC,
so this is a bit misleading, since failover and redirects are typically
used when there is not an instance in the local DC.
Add the list of common Connect CA configuration options to the
provider-specific CA docs.
Previously these options were only documented under the agent
configuration options. This change makes it so that all supported CA
provider configuration options are available from a single location.

The current suggests the option expects a string of either "enabled" or "disabled" but this results in an error `'acl.enable_key_list_policy' expected type 'bool', got unconvertible type 'string', value: 'enabled'`. Setting to a boolean value resolves this, also had a quick look at the code (d2b58cd0d6/agent/config/runtime.go (L109)) and it suggests this too

* Use CodeTabs for examples in multiple formats.

This commit adds example JSON configs for several config entry

The examples have been updated to use the new CodeTabs resource
instead of the Tab component.
The ServiceChecks parameter was incorrectly documented in e515c9d44 to

The base64 CLI utility has two different short flag arguments for decode
depending on the platform: -D and -d.
Previously, the docs used the -D flag exclusively with the base64 utility.
Luckily, the long form of the flag is the same across platforms: --decode.
All uses of the base64 -D flag have been replaced with --decode.

CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
Previously if you were to follow these docs and register two external
services, you would set the Address field on the node. The second
registered service would change the address of the node for the first
service.
Now the docs explain the address key and how to register more than one
external service.

* Docs for Unix Domain Sockets
There are a number of cases where a user might wish to either 1)
expose a service through a Unix Domain Socket in the filesystem
('downstream') or 2) connect to an upstream service by a local unix
domain socket (upstream).
As of Consul (1.10-beta2) we've added new syntax and support to configure
the Envoy proxy to support this
To connect to a service via local Unix Domain Socket instead of a
port, add local_bind_socket_path and optionally local_bind_socket_mode
to the upstream config for a service:
upstreams = [
{
destination_name = "service-1"
local_bind_socket_path = "/tmp/socket_service_1"
local_bind_socket_mode = "0700"
...
}
...
]
This will cause Envoy to create a socket with the path and mode
provided, and connect that to service-1
The mode field is optional, and if omitted will use the default mode
for Envoy. This is not applicable for abstract sockets. See
https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/core/v3/address.proto#envoy-v3-api-msg-config-core-v3-pipe
for details
NOTE: These options conflict the local_bind_socket_port and
local_bind_socket_address options. We can bind to an port or we can
bind to a socket, but not both.
To expose a service listening on a Unix Domain socket to the service
mesh use either the 'socket_path' field in the service definition or the
'local_service_socket_path' field in the proxy definition. These
fields are analogous to the 'port' and 'service_port' fields in their
respective locations.
services {
name = "service-2"
socket_path = "/tmp/socket_service_2"
...
}
OR
proxy {
local_service_socket_path = "/tmp/socket_service_2"
...
}
There is no mode field since the service is expected to create the
socket it is listening on, not the Envoy proxy.
Again, the socket_path and local_service_socket_path fields conflict
with address/port and local_service_address/local_service_port
configuration entries.
Set up a simple service mesh with dummy services:
socat -d UNIX-LISTEN:/tmp/downstream.sock,fork UNIX-CONNECT:/tmp/upstream.sock
socat -v tcp-l:4444,fork exec:/bin/cat
services {
name = "sock_forwarder"
id = "sock_forwarder.1"
socket_path = "/tmp/downstream.sock"
connect {
sidecar_service {
proxy {
upstreams = [
{
destination_name = "echo-service"
local_bind_socket_path = "/tmp/upstream.sock"
config {
passive_health_check {
interval = "10s"
max_failures = 42
}
}
}
]
}
}
}
}
services {
name = "echo-service"
port = 4444
connect = { sidecar_service {} }
Kind = "ingress-gateway"
Name = "ingress-service"
Listeners = [
{
Port = 8080
Protocol = "tcp"
Services = [
{
Name = "sock_forwarder"
}
]
}
]

This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
