Save VAULT_KV_V2 for renew

[JD-ISWT]

When issuing a certificate and deploy it for the first time, variables VAULT_PREFIX and VAULT_ADDR are save in config file for cron exec.

I don't find the way to save also VAULT_KV_V2 and correctly deploy cert one renewed with the cron.

Steps to reproduce

• Issue a cert
• deploy it using vault hook and VAULT_KV_V2 set as environment variable with VAULT_PREFIX and VAULT_ADDR
• deploy is ok
• SAVED_VAULT_PREFIX and SAVED_VAULT_ADDR are set in cert config file
• Force renew
• Renew is performed with KV_V1 scheme
