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.

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.
* LastIndexOf and always append a namespace on job links
* Confirmed the volume equivalent and simplified idWIthNamespace logic

The shortlink /s/port-plan-failure is logged when a plan for a node is
rejected to help users debug and mitigate repeated `plan for node
rejected` failures.
The current link to #9506 is... less than useful. It is not clear to
users what steps they should take to either fix their cluster or
contribute to the issue.
While .../monitoring-nomad#progess isn't as comprehensive as it could
be, it's a much more gentle introduction to the class of bug than the
original issue.

* test: use `T.TempDir` to create temporary test directory
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

Remove the step to automatically backport `backport/website` PRs to the
latest release. This will be done manually by adding the proper tags.
Also use squash backports to match the pattern we use for `main`.
