Change SSL check options in haproxy for k8s apiserver.

Haproxy option ssl-hello-chk provides simple SSLv3 check for https backend,
SSLv3 is not supported by k8s apiserver, which causes a lot of errors in log
like: "http: TLS handshake error from ...:
tls:client offered an unsupported, maximum protocol version of 300".

This patch chenges check type in haproxy to "check-ssl".
