Updates][major_versions].

This release obsoletes OkHttp 2.x, and all code that uses OkHttp's
`com.squareup.okhttp` package should upgrade to the `okhttp3` package. Libraries
that depend on OkHttp should upgrade quickly to prevent applications from being
stuck on the old version.

 *  **There is no longer a global singleton connection pool.** In OkHttp 2.x,

	// cmd represents the upgradeCheck command
	cmd := &cobra.Command{
		Use:   "precheck",
		Short: "Check whether Istio can safely be installed or upgraded",
		Long:  `precheck inspects a Kubernetes cluster for Istio install and upgrade requirements.`,
		Example: `  # Verify that Istio can be installed or upgraded
  istioctl x precheck

  # Check only a single namespace
  istioctl x precheck --namespace default
