EDA certificate management

EDA plays the following roles in certificate management:

• Generates, signs, and distribute certificates, keys, and trust-bundles to EDA components and managed nodes
• Generates a rootCA if no sub CA/CA provided during installation
• Generates a self-signed certificate for API/AS if no certificate is provided during installation; create a self-signed issuer to bootstrap a CA issuer
• Generates a certificate signing request (CSR) and sign certificates for nodes
• Generates a CSR and sign certificates for all EDA services
