Configuration for Nomad. See the <link xlink:href="https://www.nomadproject.io/docs/configuration">documentation</link>
for supported values.
Notes about `data_dir`:
If `data_dir` is set to a value other than the default value of
`"/var/lib/nomad"` it is the Nomad cluster manager's responsibility
to make sure that this directory exist and has the appropriate
permissions. One way to do this is with the `ExecStartPre` feature of
systemd.
Additionally, if `dropPrivileges` is `true` then `data_dir`
**cannot** be customized. Setting `dropPrivileges` to `true` enables
the `DynamicUser` feature of systemd which directly manages and
operates on `StateDirectory`.
