Default Cache rate limiting options in New

Pierre Souchay 947d8eb039
Added ratelimit to handle throtling cache (#8226)
This implements a solution for #7863

It does:

    Add a new config cache.entry_fetch_rate to limit the number of calls/s for a given cache entry, default value = rate.Inf
    Add cache.entry_fetch_max_burst size of rate limit (default value = 2)

The new configuration now supports the following syntax for instance to allow 1 query every 3s:

    command line HCL: -hcl 'cache = { entry_fetch_rate = 0.333}'
    in JSON

{
  "cache": {
    "entry_fetch_rate": 0.333
  }
}

Disable background cache refresh for Connect Leaf Certs
The rationale behind removing them is that all of our own code (xDS, builtin connect proxy) use the cache notification mechanism. This ensures that the blocking fetch behind the scenes is always executing. Therefore the only way you might go to get a certificate and have to wait is when 1) the request has never been made for that cert before or 2) you are using the v1/agent/connect/ca/leaf API for retrieving the cert yourself.

In the first case, the refresh change doesn’t alter the behavior. In the second case, it can be mitigated by using blocking queries with that API which just like normal cache notification mechanism will cause the blocking fetch to be initiated and to get leaf certs as soon as needed.

If you are not using blocking queries, or Envoy/xDS, or the builtin connect proxy but are retrieving the certs yourself then the HTTP endpoint might take a little longer to respond.

This also renames the RefreshTimeout field on the register options to QueryTimeout to more accurately reflect that it is used for any type that supports blocking queries.

Only pass one hostname via EDS and prefer healthy ones (#8084)
Co-authored-by: Matt Keeler <mkeeler@users.noreply.github.com>

Currently when passing hostname clusters to Envoy, we set each service instance registered with Consul as an LbEndpoint for the cluster.

However, Envoy can only handle one per cluster:
[2020-06-04 18:32:34.094][1][warning][config] [source/common/config/grpc_subscription_impl.cc:87] gRPC config for type.googleapis.com/envoy.api.v2.Cluster rejected: Error adding/updating cluster(s) dc2.internal.ddd90499-9b47-91c5-4616-c0cbf0fc358a.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint, server.dc2.consul: LOGICAL_DNS clusters must have a single locality_lb_endpoint and a single lb_endpoint

Envoy is currently handling this gracefully by only picking one of the endpoints. However, we should avoid passing multiple to avoid these warning logs.

This PR:

* Ensures we only pass one endpoint, which is tied to one service instance.
* We prefer sending an endpoint which is marked as Healthy by Consul.
* If no endpoints are healthy we emit a warning and skip the cluster.
* If multiple unique hostnames are spread across service instances we emit a warning and let the user know which will be resolved.

Enable gateways to resolve hostnames to IPv4 addresses (#7999)
The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option.

If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS.

Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.

Daniel Nephin ea6c2b2adc ci: Add staticcheck and fix most errors
Three of the checks are temporarily disabled to limit the size of the
diff, and allow us to enable all the other checks in CI.

In a follow up we can fix the issues reported by the other checks one
at a time, and enable them.

Standardize support for Tagged and BindAddresses in Ingress Gateways (#7924)
* Standardize support for Tagged and BindAddresses in Ingress Gateways

This updates the TaggedAddresses and BindAddresses behavior for Ingress
to match Mesh/Terminating gateways. The `consul connect envoy` command
now also allows passing an address without a port for tagged/bind
addresses.

Kyle Havlovitz b21cd112e5 Allow ingress gateways to route traffic based on Host header
This commit adds the necessary changes to allow an ingress gateway to
route traffic from a single defined port to multiple different upstream
services in the Consul mesh.

To do this, we now require all HTTP requests coming into the ingress
gateway to specify a Host header that matches "<service-name>.*" in
order to correctly route traffic to the correct service.

- Differentiate multiple listener's route names by port
- Adds a case in xds for allowing default discovery chains to create a
  route configuration when on an ingress gateway. This allows default
  services to easily use host header routing
- ingress-gateways have a single route config for each listener
  that utilizes domain matching to route to different services.

Daniel Nephin 1251c01b73 agent/cache: Make all cache options RegisterOptions
Previously the SupportsBlocking option was specified by a method on the
type, and all the other options were specified from RegisterOptions.

This change moves RegisterOptions to a method on the type, and moves
SupportsBlocking into the options struct.

Currently there are only 2 cache-types. So all cache-types can implement
this method by embedding a struct with those predefined values. In the
future if a cache type needs to be registered more than once with different
options it can remove the embedded type and implement the method in a way
that allows for paramaterization.
