Ansible: Replace openssl_certificate_info with command

[mnecas]

Since ansible-core 2.12 we no longer have available community modules and need to switch to commands.
The openssl_certificate_info was checking for the information of the certificate if it contained an alternative name of variable ovirt_vds_hostname. Now we are using a simple OpenSSL command query to get the alternative name openssl x509 -noout -ext subjectAltName -in FILE.
The output of the command for example is:

X509v3 Subject Alternative Name: 
    IP Address:192.168.122.164

Before we got it in subject_alt_name.

    "subject_alt_name": [
        "IP:192.168.122.164"
    ],
