revive the liveness/readiness probe config (istio#3335)
The real problem of 'crash loop' of mixer is failure of initialization; the mixer CRD store will wait for up to 30 seconds for init. (see https://github.com/istio/istio/blob/master/mixer/pkg/config/crd/store.go#L52) Considering this, this PR sets the initial delay for liveness to be 60 seconds for safety.
