CSI: validate that single-node mounts aren't used with canaries

### Nomad version

1.3.1

### Operating system and Environment details

Debian 11.3

### Issue

Hi ✋

We're running Nomad 1.3.1 with 3 nomad masters, 3 nomad clients, consul, traefik and NFS plugin.

We are facing given allocation in pending state forever. It will end by progress_deadline (10m) and failed deployment.

I am not sure if it's related to CSI, we are using NFS (https://gitlab.com/rocketduck/csi-plugin-nfs). But maybe it's not, sometimes it's happing with CSI and sometimes without.

### Reproduction steps

Take a look at job file. If I change only metadata `version=10` to `version=20`, it will stuck. Pending until progress_deadline.

If I change port to static port or dynamic port, it does not matter. Sometimes it surprisely works. :-)

#### Expected Result

Deployment will success.

#### Actual Result

Deployment failed. Allocation is still pending.

### Job file (if appropriate)

```hcl
job "canary" {
type = "service"
datacenters = ["dc1"]

meta {
version = 10
}

update {
canary = 1
max_parallel = 1
health_check = "checks"
auto_revert = true
auto_promote = true
}

group "server" {
count = 1

network {
port "http" { to = 3001 }
}

volume "canary-data" {
type = "csi"
source = "canary-data-volume"
attachment_mode = "file-system"
access_mode = "single-node-writer"
}

task "echo" {
driver = "docker"
config {
image = "hashicorp/http-echo:latest"
args = [
"-listen", ":${NOMAD_PORT_http}",
"-text", "Hello world! IP ${NOMAD_IP_http} and PORT ${NOMAD_PORT_http}",
]
ports = ["http"]
}

resources {
cpu = 128
memory = 128
}

volume_mount {
volume = "canary-data"
destination = "/app/data"
}

service {
port = "http"

tags = [
"traefik.enable=true",
"traefik.http.routers.${NOMAD_JOB_ID}.rule=Host(`canary.domain.tld`)"
]

check {
type = "http"
path = "/"
interval = "10s"
timeout = "2s"
}
}
}
}
}
```

Start by reproducing the behavior with the supplied Nomad job file, changing only the metadata version as described, and inspect the pending allocation and deployment progress deadline. Compare runs with the CSI volume and canary update settings; done means the issue has a documented validation or correction for single-node mounts used with canaries and the deployment reaches the expected successful state.
