This reverts commit b395f5bd5c5be7a3b54fc85ca482759a56a0cd6e.
Reason for revert: Breaks downstream project. Jonas will help to reland this CL.
Original change's description:
> move relay server priority assignment to port_allocator
>
> which knows more about the internals of ICE.
> Remove the relay server config priority field which was used to
> specify the relative priority of TURN servers. This is now handled
> internally by CreateRelayPortArgs without being exposed.
>
> Also rename BasicPortAllocator::AddTurnServer to
> BasicPortAllocator::AddTurnServerForTesting since it is a test-only
> method.
