MEDIUM: Add support for updating TLS ticket keys via socket

Until now, HAproxy needed to be restarted to change the TLS ticket
keys. With this patch, the TLS keys can be updated on a per-file
basis using the admin socket. Two new socket commands have been
introduced: "show tls-keys" and "set ssl tls-keys".
