Upgrade go-connlimit to v0.3.0 / return http 429 on too many connections (#8221)
Fixes #7527

I want to highlight this and explain what I think the implications are and make sure we are aware:

* `HTTPConnStateFunc` closes the connection when it is beyond the limit. `Close` does not block.
* `HTTPConnStateFuncWithDefault429Handler(10 * time.Millisecond)` blocks until the following is done (worst case):
  1) `conn.SetDeadline(10*time.Millisecond)` so that
  2) `conn.Write(429error)` is guaranteed to timeout after 10ms, so that the http 429 can be written and 
  3) `conn.Close` can happen

The implication of this change is that accepting any new connection is worst case delayed by 10ms. But only after a client reached the limit already.

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.
