https://github.com/hashicorp/nomad/pull/9608 introduced the use of the
built-in HTTP 429 response handler provided by go-connlimit. There is
concern though around plausible DOS attacks that need to be addressed,
so this PR reverts that functionality.
It keeps a fix in the tests around the use of an HTTPS enabled client
for when the server is listening on HTTPS. Previously, the tests would
fail deterministically with io.EOF because that's how the TLS server
terminates invalid connections.
Now, the result is much less deterministic. The state of the client
connection and the server socket depends on when the connection is
closed and how far along the handshake was.
CNI network configuration is currently only supported on Linux.
For now, add the linux build tag so that the deadcode linter does
not trip over unused CNI stuff on macOS.
Nomad v1.0.0 introduced a regression where the client configurations
for `connect.sidecar_image` and `connect.gateway_image` would be
ignored despite being set. This PR restores that functionality.
There was a missing layer of interpolation that needs to occur for
these parameters. Since Nomad 1.0 now supports dynamic envoy versioning
through the ${NOMAD_envoy_version} psuedo variable, we basically need
to first interpolate
${connect.sidecar_image} => envoyproxy/envoy:v${NOMAD_envoy_version}
then use Consul at runtime to resolve to a real image, e.g.
envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.16.0
Of course, if the version of Consul is too old to provide an envoy
version preference, we then need to know to fallback to the old
version of envoy that we used before.
envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.11.2@sha256:a7769160c9c1a55bb8d07a3b71ce5d64f72b1f665f10d81aa1581bc3cf850d09
Beyond that, we also need to continue to support jobs that set the
sidecar task themselves, e.g.
sidecar_task { config { image: "custom/envoy" } }
which itself could include teh pseudo envoy version variable.

In a few places Nomad was using flag implementations directly
from Consul, lending to Nomad's need to import consul. Replace
those uses with helpers already in Nomad, and copy over the bare
minimum needed to make the autopilot flags behave as they have.
Various page objects had breadcrumbs and breadcrumbFor within them, this
moves those to the existing Layout page object that contains shared page objects.
Applying the default --concurrency for gateways was missed before.
Set the default Envoy concurrency to 1 for connect gateways. The
same override value meta.connect.proxy_concurrency applies.
Instead of creating recommendations for all the jobs used
across these tests, this creates a specific job with
a higher group count, which reduces the likelihood
of having no recommendations to 0.0001%.
It was incorrect to assume that each task group would always
have recommendations, since there’s a 1% chance that a task
won’t have a recommendation. (10% chance for CPU and memory.)
This uses the number of groups with recommendations instead.
This is essentially a port of Consul's similar fix

* ci: only spin up a docker engine if necessary
Halt the website-docker-image job early if no changes are detected. We
halt early before spinning up the remote docker engine, as the remote
docker engine step can add some delay (seconds to minutes) and is more
likely to suffer circleci instability.
* ci: Only run website workflow in OSS repo
Add a CircleCI conditional to avoid running website worklows on forks.
OSS no longer needs the multi-file config Makefile content, so it was
removed. However, enterprise does benefit from having that around. We
can allow enterprise to expand on OSS' CircleCI Makefile by adding an
include directive in OSS. This will allow the Makefile to be the same on
both OSS and Enterprise, so merge conflicts cannot occur.
Previously, Nomad would fail to startup if the CPU fingerprinter could
not detect the cpu total compute (i.e. cores * mhz). This is common on
some EC2 instance types (graviton class), where the env_aws fingerprinter
will override the detected CPU performance with a more accurate value
anyway.
Instead of crashing on startup, have Nomad use a low default for available
cpu performance of 1000 ticks (e.g. 1 core * 1 GHz). This enables Nomad
to get past the useless cpu fingerprinting on those EC2 instances. The
crashing error message is now a log statement suggesting the setting of
cpu_total_compute in client config.
Fixes#7989
