Packer hangs and ctrl+c does not abort when OCI region is out of capacity.

#### Overview of the Issue

## Note: See debug log, Out of Capacity is clearly communicated by the OCI SDK, just packer does not handle it.

When an OCI region is out of Capacity, the OCI WebUI will present the following error:

> Out of capacity for shape VM.Standard.E4.Flex in availability domain AD-1. Create the instance in a different availability domain or try again later. If you're using a previous generation shape, please create the instance using a current generation shape instead. For current generation shapes, create the instance in a different availability domain, avoid choosing a fault domain, use a smaller shape or different shape series, or wait a few minutes and try again.

However, packer just hangs, and there are no messages after `Creating instance...`
```bash
$ packer build -only=oracle-oci.jed-amd64 templates/debug/.
oracle-oci.jed-amd64: output will be in this color.

==> oracle-oci.jed-amd64: Creating temporary ssh key for instance...
==> oracle-oci.jed-amd64: Creating instance...
Cancelling build after receiving interrupt
```

Hitting CTRL+C just results in `Cancelling build after receiving interrupt`, but it never actually cleans up.

#### Reproduction Steps

Enable debug logging on both packer and the OCI sdk, if you dont do this for the OCI SDK, the logs are useless.
```bash
export PACKER_LOG=1
export PACKER_LOG_PATH="packer.log"
export OCI_GO_SDK_DEBUG=verbose
```

Deploy to OCI region that has insufficient Capacity, example: any E4 flex size to JED, or large E4 sizes to IAD-AD1 at certain times of day.

### Plugin and Packer version

Packer v1.8.3

### Simplified Packer Buildfile

The only values you need to fix are the compartment_ocid, and the regional public subnet ids within that compartment:
```hcl
variable "compartment_ocid" {
type = string
description = "Compartment ID to build the image"
default = "ocid1.compartment.oc1..aaaaaaaaaaaaaaaa"
}
variables {
regions = {
iad = {
region = "us-ashburn-1"
region_ad = "YOUR_ACCOUNT_AD_PREFIX_HERE:US-ASHBURN-AD-1"
subnet_ocid = "ocid1.subnet.oc1.iad.aaaaaaaaaaaaaaaa"
}
jed = {
region = "me-jeddah-1"
region_ad = "YOUR_ACCOUNT_AD_PREFIX_HERE:ME-JEDDAH-1-AD-1"
subnet_ocid = "ocid1.subnet.oc1.me-jeddah-1.aaaaaaaaaaaaaaaa"
}
}
}
```
Everything else below is as needed to run.

```hcl
// export PACKER_LOG=1
// export PACKER_LOG_PATH="packer.log"
// export OCI_GO_SDK_DEBUG=verbose
// packer build -only=oracle-oci.jed-amd64 templates/debug/.
