Increase Galera self-signed SSL CA expiration
Increase Galera self-signed SSL CA expiration

Currently we generate the CA certificate with default expiration time (30
days), while both CSR and signed certificates are set to expire in 3650 days.
If a Galera service is restarted after 30 days, replication breaks due to
expired CA certificate.

Increasing the CA certificate expiration to 3650 days resolves the issue and
makes expiration consistent between the certificates.
