### TODO

In subsequent releases we are planning to extend this to provide things like

		if opts != nil && opts.CADir != "" {
			rootCAs, err = certs.GetRootCAs(opts.CADir)
			if err != nil {
				return nil, err
			}
		}

		client, err := kms.NewClient(&kms.Config{
			Endpoints: endpoints,
			APIKey:    key,
			TLS: &tls.Config{
				MinVersion:         tls.VersionTLS12,
				ClientSessionCache: tls.NewLRUClientSessionCache(tlsClientSessionCacheSize),
				RootCAs:            rootCAs,
			},
		})
