i found this confusing since 8300 is associated with consul. suggest using more nomad ports

Add initial Dependabot configuration

This fixes a bug in the event stream API where it currently interprets
namespace=* as an actual namespace, not a wildcard. When Nomad parses
incoming requests, it sets namespace to default if not specified, which
means the request namespace will never be an empty string, which is what
the event subscription was checking for. This changes the conditional
logic to check for a wildcard namespace instead of an empty one.

It also updates some event tests to include the default namespace in the
subscription to match current behavior.

Fixes #10903

Also format terraform scripts with hclfmt, equivalent to terraform fmt.

I opted not to use terraform fmt, because I didn't want to introduce dev dependency on the terraform CLI.

Also, I've optimized the find command to ignore spurious directories (e.g. .git, node_modules) that seem to be populated with too many files! make hclfmt takes 0.3s on my mac down from 7 seconds!

updated with Nomad ports and web link (learn guide: https://learn.hashicorp.com/tutorials/nomad/outage-recovery)

Mention the ndjson standard format the event stream uses

scripts: create CNI config directory within Vagrant machine.

This PR adds a sentence about configuring your firewall to allow required Nomad ports. This is being added to help search discoverability.

This closes issue #11076

chore: fix incorrect docstring formatting.

Knowing this upfront is important when looking for common libraries to help consume events.

This allows us to spin up e2e clusters with mTLS configured for all HashiCorp services, i.e. Nomad, Consul, and Vault. Used it for testing #11089 .

mTLS is disabled by default. I have not updated Windows provisioning scripts yet - Windows also lacks ACL support from before. I intend to follow up for them in another round.

Deflake tests attempts

Attempt to deflake the test by avoiding shutting down the leaders, as leadership
recovery takes more time, and consequently longer to process raft configuration
changes and potentially failing the test.

Wait for leadership to be established before killing leader.

When a node becomes ready, create an eval for all system jobs across
namespaces.

The previous code uses `job.ID` to deduplicate evals, but that ignores
the job namespace. Thus if there are multiple jobs in different
namespaces sharing the same ID/Name, only one will be considered for
running in the new node. Thus, Nomad may skip running some system jobs
in that node.

Target all e2e datacenters for system and sysbatch e2e tests.  They
require that the system jobs run on all linux clients.

However, the jobs currenly only target `dc1` datacenter, but the nightly
e2e cluster has 4 clients spread in `dc1` and `dc2` datacenters, causing
the tests to fail.

I missed this problem in e2e dev cluster because it only used a single
dc1 datacenter.
