docs: Miscellaneous docs cleanup (#6742)
Fix spelling errors, API doc inconsistencies, and formatting issues.

* Fix several spelling errors.
* Prepend / to v1/event/list path in Watches.
* Rename script handlers to match Watch type.
* Remove /v1 path prefix on service health API endpoints.

Makes request path consistent with the rest of the HTTP API
documentation which does not include the /v1 prefix.

* Fix bracket formatting issue on Telemetry page.

The HTML codes used for brackets inside of the code block are not
interpolated, and are shown as literal strings.

Replace the numeric HTML codes with the intended character value to
fix display formatting.

Also placed variable reference on agent/options.html inside code block
for consistency with the presentation of other options on the page.

* Add missing word to Coordinate.Node docstring.

Resolves #6014

Freddy 2eaece10a7
Update Force Leave docs (#6550)
Fixes #2742

Previously the docs didn't clarify that if a server restarts as a client then force-leave won't lead to removing the node from the raft config. This is because the node, which is alive after a restart, will refute messages about it having left . These messages about members leaving are in turn what trigger Consul's leader to remove a server from raft.

Expose HTTP-based paths through Connect proxy (#6446)
Fixes: #5396

This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.

Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.

This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.

Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.

In this initial implementation requests to these paths are not
authenticated/encrypted.

The fields in the certs are meant to hold the original binary

The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).

Nick Fagerlund ce8a27aedc website: Update middleman-hashicorp container and Gemfile.lock (#6374)
* website: Update middleman-hashicorp container and Gemfile.lock

Time marches on, and so do security vulnerabilities in Nokogiri. So it's time
for a new container.

As with last time, here's a reminder for the next person who needs to update
this:

- You shouldn't just update the dependency in Gemfile.lock, because your build
  times will go to heck as you compile Nokogiri from source on every run. So you
  need an updated container with all the dependencies.
- To update the container, you need to push a new tag to the middleman-hashicorp
  repo. Teamcity does the rest, and will ship a new container to Docker Hub
  (unless its credentials are out of date, in which case go ask team-eng-serv.)
- Once that's pushed:
    - Update Makefile
    - Update the Gemfile
    - Delete Gemfile.lock
    - `make website` until it comes up, then ctrl-C
    - Commit the changes

* website: Specify a different json version in Gemfile.lock

The Consul website uses different containers for preview and deploy, and this
oddball JSON version was causing issues. This commit sacrifices a little bit
of preview startup speed for (hopefully) working deploys.

R.B. Boyer e039dfd7f8
connect: rework how the service resolver subset OnlyPassing flag works (#6173)
The main change is that we no longer filter service instances by health,
preferring instead to render all results down into EDS endpoints in
envoy and merely label the endpoints as HEALTHY or UNHEALTHY.

When OnlyPassing is set to true we will force consul checks in a
'warning' state to render as UNHEALTHY in envoy.

Fixes #6171

Allow raft TrailingLogs to be configured. (#6186)
This fixes pathological cases where the write throughput and snapshot size are both so large that more than 10k log entries are written in the time it takes to restore the snapshot from disk. In this case followers that restart can never catch up with leader replication again and enter a loop of constantly downloading a full snapshot and restoring it only to find that snapshot is already out of date and the leader has truncated its logs so a new snapshot is sent etc.

In general if you need to adjust this, you are probably abusing Consul for purposes outside its design envelope and should reconsider your usage to reduce data size and/or write volume.
