OpenStack Builder: source_image_filter with wildcards for "name" field

_This issue was originally opened by @stefankaufmann as hashicorp/packer#10675. It was migrated here as a result of the [Packer plugin split](https://github.com/hashicorp/packer/issues/8610#issuecomment-770034737). The original body of the issue is below._

#### Description

When using the OpenStack Builder, there is no possibility to filter for source images which contain a certain string in its name.
The feature should work like https://www.packer.io/docs/builders/amazon/ebs#source_ami_filter

#### Use Case(s)

Our openstack is set up to automatically sync base images for different ubuntu versions. Since timestamps are contained in the name of the image, we always need to change the base image accordingly. This could be prevented if this feature was present.

The configuration could look like
```
"source_image_filter": {
"name" : "auto-sync/ubuntu-focal-*"
}
```
