    CI: Lower memory usage of VMs/Increase swap
    
    The IPA images we presently build/use for centos are
    now smaller than their peak size a few months ago.
    
    As such, we should be able to reduce that memory footprint
    and still execcute all of the necessary tests without any
    issues.
    
    Also increases the amount of swap to 8GB as the infra
    default is now 1GB.
