Daniel Nephin 04c5b9adf5 rpcclient: Add health.Client and use it in http and dns
This new package provides a client agent implementation of an interface
for fetching the health of services.

This approach has a number of benefits:

1. It provides a much more explicit interface. Instead of everything
   dependency on `RPC()` and `Cache.Get()` for many unrelated things
   they can depend on a type that are named according to the behaviour
   it provides.

2. It gives us a single place to vary the behaviour and migrate to
   a new form of RPC (gRPC). The current implementation has two options
   (cache, or direct RPC), and in the future we will have more.
   It is also a great opporunity to start adding `context.Context` args
   to these operations, which in the future will allow us to cancel
   the operations.

3. As a concequence of the first, in the Server agent where we make
   these calls we can replace the current in-memory RPC calls with
   a thin adapter for the real method. This removes the `net/rpc`
   machinery from the call in places where it is not needed.

This new package is quite small right now, but I think we can expect it
to grow to a more reasonable size as other RPC calls are replaced.

This change also happens to replace two very similar implementations with
a single implementation.

Consul CircleCI Discuss

Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.

Consul provides several key features:

  • Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.

  • Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.

  • Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.

  • Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.

  • Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.

Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.

Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
