This PR updates the tags that we generate for Envoy stats.
Several of these come with breaking changes, since we can't keep two stats prefixes for a filter.
When consul is restarted and an envoy that had already sent
DiscoveryRequests to the previous consul process sends a request to the
new process it doesn't respect the setting and never populates
DiscoveryRequest.Node for the life of the new consul process due to this
bug: https://github.com/envoyproxy/envoy/issues/9682Fixes#8430
The new grpcAddress function contains all of the logic to translate the
command line options into the values used in the template.
The new type has two advantages.
1. It introduces a logical grouping of values in the BootstrapTplArgs
struct which is exceptionally large. This grouping makes the struct
easier to understand because each set of nested values can be seen
as a single entity.
2. It gives us a reasonable return value for this new function.
* add 1.12.2
* add envoy 1.13.0
* Introduce -envoy-version to get 1.10.0 passing.
* update old version and fix consul-exec case
* add envoy_version and fix check
* Update Envoy CLI tests to account for the 1.13 compatibility changes.

* connect: allow overriding envoy listener bind_address
* Update agent/xds/config.go

* connect: allow overriding envoy listener bind_port
* envoy: support unix sockets for grpc in bootstrap
Add AgentSocket BootstrapTplArgs which if set overrides the AgentAddress
and AgentPort to generate a bootstrap which points Envoy to a unix
socket file instead of an ip:port.
* Add a test for passing the consul addr as a unix socket
* Fix config formatting for envoy bootstrap tests
* Fix listeners test cases for bind addr/port
* Update website/source/docs/connect/proxies/envoy.md
* Add support for HTTP proxy listeners
* Add customizable bootstrap configuration options
* Debug logging for xDS AuthZ
* Add Envoy Integration test suite with basic test coverage
* Add envoy command tests to cover new cases
* Add tracing integration test
* Add gRPC support WIP
* Merged changes from master Docker. get CI integration to work with same Dockerfile now
* Make docker build optional for integration
* Enable integration tests again!
* http2 and grpc integration tests and fixes
* Fix up command config tests
* Store all container logs as artifacts in circle on fail
* Add retries to outer part of stats measurements as we keep missing them in CI
* Only dump logs on failing cases
* Fix typos from code review
* Review tidying and make tests pass again
* Add debug logs to exec test.
* Fix legit test failure caused by upstream rename in envoy config
* Attempt to reduce cases of bad TLS handshake in CI integration tests
* bring up the right service
* Add prometheus integration test
* Add test for denied AuthZ both HTTP and TCP
* Try ANSI term for Circle
* Default gRPC port; Start on some basic tests for argument and ENV handling; Make Exec test less platform-dependent.
* Allow hot-restarts
* Remove debug
Play a trick with CLOEXEC to pass the envoy bootstrap configuration as
an open file descriptor to the exec'd envoy process. The file only
briefly touches disk before being unlinked.
We convince envoy to read from this open file descriptor by using the
/dev/fd/$FDNUMBER mechanism to read the open file descriptor as a file.
Because the filename no longer has an extension envoy's sniffing logic
falls back on JSON instead of YAML, so the bootstrap configuration must
be generated as JSON instead.
* Plumb xDS server and proxyxfg into the agent startup
* Add `consul connect envoy` command to allow running Envoy as a connect sidecar.
* Add test for help tabs; typos and style fixups from review
