[FLINK-12199] Refactor IOMetrics to not distinguish between local/remote in/out bytes

Description

At the moment we have numBytesInLocal/numBytesInRemote in IOMetrics but in the actual usage we just always sum them up. As local/remote is the detail of shuffle service implementation, we can merge the local/remote metrics into one and increment it later in Task instead of remote/local channels in network internals.
