Add failures_before_warning to checks (#10969)
Signed-off-by: Jakub Sokołowski <jakub@status.im>

* 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.

Consul API client

This package provides the api package which attempts to provide programmatic access to the full Consul API.

Currently, all of the Consul APIs included in version 0.6.0 are supported.

Documentation

The full documentation is available on Godoc

Usage

Below is an example of using the Consul client:

package main

import "github.com/hashicorp/consul/api"
import "fmt"

func main() {
	// Get a new client
	client, err := api.NewClient(api.DefaultConfig())
	if err != nil {
		panic(err)
	}

	// Get a handle to the KV API
	kv := client.KV()

	// PUT a new KV pair
	p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
	_, err = kv.Put(p, nil)
	if err != nil {
		panic(err)
	}

	// Lookup the pair
	pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
	if err != nil {
		panic(err)
	}
	fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
}

To run this example, start a Consul server:

consul agent -dev

Copy the code above into a file such as main.go.

Install and run. You'll see a key (REDIS_MAXCLIENTS) and value (1000) printed.

$ go get
$ go run main.go
KV: REDIS_MAXCLIENTS 1000

After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv
