add dotnetty.common reference to 0.7.1 (#6122)

Reference dotnetty.common 0.7.1 to force using this version because it has a fix for bug introduced in 0.7.0 which client SDK uses. Bug causes edgeHub process to not be terminated for certificate renewal when UpstreamProtocol is Mqtt

Tested manually that edgeHub shutdown works when UpstreamProtocol is Mqtt and added e2e test for Mqtt.
