On a few occasions I've had to read timeout stack traces for tests and noticed that retry.Run runs the function in a goroutine. This makes debuging a timeout more difficult because the gourinte of the retryable function is disconnected from the stack of the actual test. It requires searching through the entire stack trace to find the other goroutine. By using panic instead of runtime.Goexit() we remove the need for a separate goroutine. Also a few other small improvements: * add `R.Helper` so that an assertion function can be used with both testing.T and retry.R. * Pass t to `Retryer.NextOr`, and call `t.Helper` in a number of places so that the line number reported by `t.Log` is the line in the test where `retry.Run` was called, instead of some line in `retry.go` that is not relevant to the failure. * improve the implementation of `dedup` by removing the need to iterate twice. Instad track the lines and skip any duplicate when writing to the buffer.

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.
