Both LXC and QEMU drivers have the same code to remove vport when removing a domain's interface. Instead of repeating the same pattern in both drivers, move the code into hypervisor agnostic location (src/hypervisor/) and switch to calling this new function.

The reason virDomainClearNetBandwidth() exists in src/conf/ is that at the time its introduction we did not have a better place. But now we do. Firstly, virDomainClearNetBandwidth() is hypervisor agnostic code, but really has nothing to do with domain configuration (it doesn't parse/format XML). Secondly, in near future it'll call another function from src/hypervisor/ and that's not really allowed from src/conf/.

In QEMU and LXC drivers in a few places just virNetDevBandwidthClear() is called. This means that if an interface is of openvswitch vport profile, its QoS is not removed. And to make matters worse - OVS is designed to remember state even when corresponding interface is gone. This leads to stale QoS settings piling up in OVS database. To resolve this, introduce virDomainInterfaceClearQoS() which looks at given interface and calls corresponding QoS clear function. Then, basically replace virNetDevBandwidthClear() calls in those hypervisor drivers with this new function.
