We want to start providing Mac instances for testing for the Containers team as agreed on DevConf.cz 2024 with @mohanboddu and @davdunc.

For this we need to be able to allocate dedicated hosts, what seems to be a requirement for provisioning these instances.

We need at least this permission for aws-fedora-ci, including the automation account:

```
You are not authorized to perform this operation. User: arn:aws:sts::125523088429:assumed-role/aws-fedora-ci/mvadkert is not authorized to perform: ec2:AllocateHosts on resource: arn:aws:ec2:us-east-1:125523088429:dedicated-host/* because no identity-based policy allows the ec2:AllocateHosts action
```
