Allow for readiness type checks by configuring nomad to ignore warnings
or errors reported by a service check. This allows the deployment to
progress and while Consul handles introducing the sercive into a
resource pool once the check passes.
This PR adds default_pid_mode and default_ipc_mode options to the exec and java
task drivers. By default these will default to "private" mode, enabling PID and
IPC isolation for tasks. Setting them to "host" mode disables isolation. Doing
so is not recommended, but may be necessary to support legacy job configurations.
Closes#9969
The details of host volume and CSI volume requests do not show up in `nomad
plan` outputs, although the updates are detected by the scheduler and result
in an update as expected.
This closes#9966. It was looking at the query parameters
for the namespace and region, but allocation (and task!)
routes don’t have a namespace query parameter. Since the URL
generator requires the job for all calls, it makes sense to
extract the namespace and region from the job instead.
- aws secret key is named incorrectly in the target docs.
It needs to match what is in the nomad-autoscaler repo
(see link below), otherwise the autoscaler will default to AWS sdk
behavior, which could end up using an IAM instance profile
or other environment variables instead of what is passed into the
autoscaler config file.

Allow expressing `meta` and `env` blocks as map attributes as well.
`env` and `meta` should support arbitrary key and values, yet hcl2
restricts the keys to valid identifiers. For example, block attribute
identifiers may not contain dots, `.`, which frequently used in meta
fields, and sometimes in environment variable fields.
By adding attribute syntax support, we maintain backward compatibility and relax the block attribute key restrictions. This change attempts to parse `env`/`meta` both as an attribute and as a
block.
Additionally, the change allows better expressivity for env/meta blocks, using
functions and for expressions. For example, one can reuse a set of environment variables for
multiple tasks, using a local `common_envs` value:
```hcl
env = merge(local.common_envs, {"more_env_key", "..."})
```
Note that the map/attribute compatibility workaround is currently a pattern we recommend for driver config blocks: https://www.nomadproject.io/docs/job-specification/hcl2#blocks . :( Sadly, the document isn't accurate, as only `meta` appearing inside driver config was handled in 1.0.1.

The region will naturally be appended to URLs via
token.authorizedRequest but agent members includes all servers across
all regions so relying on the application-level region isn't good
enough.
