Fixes typo in word "failed".
Fixes bug where incorrect error is printed. The old code would only
ever print a nil error, instead of the validationErr which is being
created.
`admissionValidators` doesn't aggregate errors correctly, as it
aggregates errors in `errs` reference yet it always returns the nil
`err`.
Here, we avoid shadowing `err`, and move variable declarations to where
they are used.
`groupConnectHook` assumes that Networks is a non-empty slice, but TG
hasn't been validated yet and validation may depend on mutation results.
As such, we do basic check here before dereferencing network slice
elements.
Vault 1.2.0 deprecated `period` field in favor of `token_period` in auth
role:
> * Token store roles use new, common token fields for the values
> that overlap with other auth backends. `period`, `explicit_max_ttl`, and
> `bound_cidrs` will continue to work, with priority being given to the
> `token_` prefixed versions of those parameters. They will also be returned
> when doing a read on the role if they were used to provide values initially;
> however, in Vault 1.4 if `period` or `explicit_max_ttl` is zero they will no
> longer be returned. (`explicit_max_ttl` was already not returned if empty.)

Ensure that we're reusing the base configuration between client and
servers without the possibility of drift. Reduce the amount of `sed`
mangling of the configuration file, and make recommended changes from
`shellcheck` for this section of the provisioning script.
Fixes some rebase errors on the Nomad config as well.
Share base configuration for telemetry and consul. Have the server
configurations respect the `var.server_count` config. Make changes
recommended by `shellcheck` in the provisioning scripts for this section.
Switch to OS/arch-tagged release bundles on S3 for compatibility with
adding Windows builds in the near future.
Match the configuration directory layout we're using for Consul and
other services. Make recommended changes from `shellcheck` for this
section of the provisioning script.
Update the Consul and Vault configs to take advantage of their
included `go-sockaddr` library for getting the IP addresses we need in
a portable way. This particularly avoids problems with "predictable"
interface names provided by systemd.
Also adds the `sockaddr` binary to the Packer build so we can use it
in our provisioning scripts.
Make a clear split between Packer and Terraform provisioning steps:
the scripts in the `packer/linux` directory are run when we build the
AMI whereas the stuff in shared are run at Terraform provisioning time.
Merging all runtime provisioning scripts into a single script for each
of server/client solves the following:
* Userdata scripts can't take arguments, they can only be templated
and that means we have to do TF escaping in bash/powershell scripts.
* TF provisioning scripts race with userdata scripts.
* add nginx to load balancing nav menu and fix bullets
* fill out nginx lb guide
* formatting
* change Nginx to NGINX
* add step to verify load balancer config
* update docker image and web app output
* change Nginx to NGINX in main load balancing page
* modify change signal to SIGHUP and add else condition in template stanza to prevent nginx from crashing when no services are available to load balance
* add note about external load balancer
* clarifications and link to reference architecture
As the angle bracket invocation RFC says:

Unfortunately, using a contextual component doesn’t help as
the yield inside that component will still result in content
rendering that would show when the source isn’t empty. So
we decided to change the interface so you have to check
whether the source is empty before using it, which aligns with
how list-table works.
* changed list indicator from * -> -
* moved in-text links to reference links
* made commands `plaintext`
* made command examples `console`
* rewrapped text
