prevent memory leak under high client churn

Start-Stop-Start cycles; guard double-close in Stop()
- resolver/resolver.go: recreate stopCh in Start() to support restart

scheduleRotation with mu; support Start-Stop-Start cycles
- ssl/ssl.go: cache parsed default certificate to avoid re-parsing on
every TLS handshake for OCSP stapling
