mismatch between the key and the certificate signature algorithm

[soumiksamanta]

1. Create a selfsigned issuer
2. Create a CA certificate using the selfsigned issuer. Make sure the algorithm used in ECDSA
3. Create an issuer from the above generated CA
4. Use CSI driver
   Using openssl s_client -connect, its observed that the key is RSA while the cert is ECDSA

[openssl s_client -connect](a:PKEY: rsaEncryption, 2048 (bit); sigalg: ecdsa-with-SHA256)

The CSI driver should create the key as the issuer which is ecdsa in this case
