Add a new envoy flag: "envoy_hcp_metrics_bind_socket_dir", a directory
where a unix socket will be created with the name
`<namespace>_<proxy_id>.sock` to forward Envoy metrics.
If set, this will configure:
- In bootstrap configuration a local stats_sink and static cluster.
These will forward metrics to a loopback listener sent over xDS.
- A dynamic listener listening at the socket path that the previously
defined static cluster is sending metrics to.
- A dynamic cluster that will forward traffic received at this listener
to the hcp-metrics-collector service.
Reasons for having a static cluster pointing at a dynamic listener:
- We want to secure the metrics stream using TLS, but the stats sink can
only be defined in bootstrap config. With dynamic listeners/clusters
we can use the proxy's leaf certificate issued by the Connect CA,
which isn't available at bootstrap time.
- We want to intelligently route to the HCP collector. Configuring its
addreess at bootstrap time limits our flexibility routing-wise. More
on this below.
Reasons for defining the collector as an upstream in `proxycfg`:
- The HCP collector will be deployed as a mesh service.
- Certificate management is taken care of, as mentioned above.
- Service discovery and routing logic is automatically taken care of,
meaning that no code changes are required in the xds package.
- Custom routing rules can be added for the collector using discovery
chain config entries. Initially the collector is expected to be
deployed to each admin partition, but in the future could be deployed
centrally in the default partition. These config entries could even be
managed by HCP itself.
* Add support for envoy readiness flags
- add flags 'envoy-ready-bind-port` and `envoy-ready-bind-addr` on consul connect envoy to create a ready listener on that address.

* add functions for returning the max and min Envoy major versions
- added an UnsupportedEnvoyVersions list
- removed an unused error from TestDetermineSupportedProxyFeaturesFromString
- modified minSupportedVersion to use the function for getting the Min Envoy major version. Using just the major version without the patch is equivalent to using `.0`
* added a function for executing the envoy --version command
- added a new exec.go file to not be locked to unix system
* added envoy version check when using consul connect envoy
* added changelog entry
* added docs change
Use long form of CLI flags in all example commands.

The only thing that needed fixing up pertained to this section of the 1.18.x release notes:
> grpc_stats: the default value for stats_for_all_methods is switched from true to false, in order to avoid possible memory exhaustion due to an untrusted downstream sending a large number of unique method names. The previous default value was deprecated in version 1.14.0. This only changes the behavior when the value is not set. The previous behavior can be used by setting the value to true. This behavior change by be overridden by setting runtime feature envoy.deprecated_features.grpc_stats_filter_enable_stats_for_all_methods_by_default.
For now to maintain status-quo I'm explicitly setting `stats_for_all_methods=true` in all versions to avoid relying upon the default.
Additionally the naming of the emitted metrics for these gRPC requests changed slightly so the integration test assertions for `case-grpc` needed adjusting.
* Add new consul connect redirect-traffic command for applying traffic redirection rules when Transparent Proxy is enabled.
* Add new iptables package for applying traffic redirection rules with iptables.
* website: migrate to new nav-data format
* website: clean up unused intro content
* website: remove deprecated sidebar_title from frontmatter
* website: add react-content to fix global style import issue
Allows setting -prometheus-backend-port to configure the cluster
envoy_prometheus_bind_addr points to.
Allows setting -prometheus-scrape-path to configure which path
envoy_prometheus_bind_addr exposes metrics on.
-prometheus-backend-port is used by the consul-k8s metrics merging feature, to
configure envoy_prometheus_bind_addr to point to the merged metrics
endpoint that combines Envoy and service metrics so that one set of
annotations on a Pod can scrape metrics from the service and it's Envoy
sidecar.
-prometheus-scrape-path is used to allow configurability of the path
where prometheus metrics are exposed on envoy_prometheus_bind_addr.
