Description

As per the Tiered Storage feature introduced in KIP-405, we added several metrics related to reads(from) and writes(to) for remote storage. The naming convention that was followed is confusing to the users.

For eg. in regular Kafka, BytesIn means bytes written to the log, and BytesOut means bytes read from the log. But with tiered storage, the concepts are reversed.

• RemoteBytesIn means "Number of bytes read from remote storage per second"
• RemoteBytesOut means "Number of bytes written to remote storage per second"

We should rename the tiered storage related metrics to remove any ambiguity.
