In addition to jobs, there are other objects in Nomad that have a
specific format and can be provided to commands and API endpoints.
This commit creates a new menu section to hold the specification for
volumes and update the command pages to point to the new centralized
definition.
Redirecting the previous entries is not possible with `redirect.js`
because they are done server-side and URL fragments are not accessible
to detect a match. So we provide hidden anchors with a link to the new
page to guide users towards the new documentation.

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"]`.
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.
Closes#12927Closes#12958
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.
