This PR adds the ability to set HTTP headers when downloading
an artifact from an `http` or `https` resource.
The implementation in `go-getter` is such that a new `HTTPGetter`
must be created for each artifact that sets headers (as opposed
to conveniently setting headers per-request). This PR maintains
the memoization of the default Getter objects, creating new ones
only for artifacts where headers are set.
Closes#9306
Update the default value for `client.bridge_network_subnet` in docs
to match the new value from 99742f2665. Was `172.26.66.0/23`, is
now `172.26.64.0/20`.
Fixes#9316
The default behavior for `docker.volumes.enabled` is intended to be `false`,
but the HCL schema defaults to `true` if the value is unset. Set the default
literal value to `true`.
Additionally, Docker driver mounts of type "volume" (but not "bind") are not
being properly sandboxed with that setting. Disable Docker mounts with type
"volume" entirely whenever the `docker.volumes.enabled` flag is set to
false. Note this is unrelated to the `volume_mount` feature, which is
constrained to preconfigured host volumes or whatever is mounted by a CSI
plugin.
This changeset includes updates to unit tests that should have been failing
under the documented behavior but were not.
We recently added documentation disambiguating the terminology of the
allocation/task working directories. This changeset adds an internals document
that describes in more detail exactly what does into the allocation working
directory, how this interacts with the filesystem isolation provided by task
drivers, and how this interacts with features like `artifact` and `template`.

This is a first draft of HCLv2 docs - I added the details under hcl2 doc with some minimal info highlighting the hcl2 introductions.
As a longer term strategy, we'll want to mimic the Packer HCL docs structure that details all the blocks and allowed expressions/functions in greater details. However, given that the exact functions and templating syntax is still somewhat influx, I opt to push that to another time.
The `template.allow_host_source` configuration was not operable, leading to
the recent security patch in 0.12.6. We forgot to update this piece of the
documentation referring to the correct configuration value.
Beforehand tasks and field replacements did not have access to the
unique ID of their job or its parent. This adds this information as
new environment variables.
* remove event durability
temporarily removing go-memdb event durability until a new strategy is developed on how to best handled increased durability needs
* drop events table schema and state store methods
* fix neweventbuffer invocations
The terms task directory and allocation directory are used throughout the
documentation but these directories are not the same as the `NOMAD_TASK_DIR`
and `NOMAD_ALLOC_DIR` locations. This is confusing when trying to use the
`template` and `artifact` stanzas, especially when trying to use a destination
outside the Nomad-mounted directories for Docker and similar drivers.
This changeset introduces "allocation working directory" to mean the location
on disk where the various directories and artifacts are staged, and "task
working directory" for the task. Clarify how specific task drivers interact
with the task working directory.
