Description

In the read path, the validation of the response while reading the data from the datanodes happen in XceiverClientGrpc as well as additional  Checksum verification happens in Ozone client to verify the read chunk response. The aim of this Jira is to modify the function call to take a validator function as a part of reading data so all validation can happen in a single unified place.
