--peer-auto-tls cert is valid only for 1 year, is there a way to set expiry date?

[sreenandan]

2 questions:

1. How to set the expiry of peer certificate when using --peer-auto-tls?
2. If point 1 above is not possible, can you please give me cfssl command to generate my own cert just like --peer-auto-tls?
   I tried https://github.com/coreos/docs/blob/master/os/generate-self-signed-certificates.md and certs come with Signature Algorithm: sha256WithRSAEncryption and it wont work because of ip mismatch.
   So, basically my question here is how to use cfssl command to generate the certs just like --peer-auto-tls?
