Override parameters in template file from cli

### Description

Hi.
I wonder if it's possible to override template parameters via limactl?
For example:
```bash
limactl start --name=default --template=default.yml --cpus=1 --memory=2GiB
```

If it's not very difficult I can contribute with some guidance.
