This PR update to Go 1.18.2. Also update the versions of hclfmt
and go-hclogfmt which includes newer dependencies necessary for dealing
with go1.18.
The hcl v2 branch is now 'nomad-v2.9.1+tweaks2', to include a fix for
newer macOS versions: 8927e75e82
Fix numerous go-getter security issues:
- Add timeouts to http, git, and hg operations to prevent DoS
- Add size limit to http to prevent resource exhaustion
- Disable following symlinks in both artifacts and `job run`
- Stop performing initial HEAD request to avoid file corruption on
retries and DoS opportunities.
**Approach**
Since Nomad has no ability to differentiate a DoS-via-large-artifact vs
a legitimate workload, all of the new limits are configurable at the
client agent level.
The max size of HTTP downloads is also exposed as a node attribute so
that if some workloads have large artifacts they can specify a high
limit in their jobspecs.
In the future all of this plumbing could be extended to enable/disable
specific getters or artifact downloading entirely on a per-node basis.
The description of `mount_flags` provides incorrect example
of the accepted value format.
This fixes the issue by changing the example from a string
`ro,noatime` to a slice of strings `["ro", "noatime"]`.
The nightly playwright tests are currently failing because of a
mismatch between the expected version of Chromium and what's in the
container image. Unfortunately the previous specific tag we were using
for the container image is no longer tagged on the registry. With some
testing, I was able to find an image tag that results in a good run.
Nomad errors out when attempting to specify a task for a service that uses consul connect but does not have script or gRPC checks. See 304d0cf595/nomad/structs/structs.go (L6643) for details.

This PR updates the version of redis used in our examples from 3.2 to 7.
The old version is very not supported anymore, and we should be setting
a good example by using a supported version.
The long-form example job is now fixed so that the service stanza uses
nomad as the service discovery provider, and so now the job runs without
a requirement of having Consul running and configured.
