BUG-Error loading passphraseless certificate with empty passphrase field

[mrnetops]

Error when attempting to update a certificate without a passphrase (when no passphrase is present on the certificate)

Encountered an error on POST request to URL https://xx.xx.xx.xx/api/sslkeyandcertificate: HTTP code: 400; error from Avi: map[error:Incomplete Input SSLKeyAndCertificate]

I SUSPECT somewhere in the code (probably around github.com/lbapi/certificate/model.go), lbAPI incorrectly always requires a passphrase for the struct and falls over if it's not present.
