    Tests: force key type in ACME tests
    
    PKI can issue ACME certs only when the key type is rsa.
    
    With version 2.0.0, certbot defaults to ecdsa key type,
    and this causes test failures.
    For now, force rsa when requesting an ACME certificate.
    This change can be reverted when PKI fixes the issue
    on their side (https://github.com/dogtagpki/pki/issues/4273)
