Review comment:
@bharat, if we use acquireClientForReadData, it will use XceiverClientGrpc
to read the info rather than Ratis(which reads from the leader).
XceiverClientGrpc automatically fails over from datanode to another if it sees
a failure.
InfoSubCommand has recently been changed to not use readContainer call to
read data from datanode. But , in Ozone, we only use XceiverClientGrpc to read
from datanode , it make sense here to use the same while reading the
containerData as well (acquireClient -> acquireClientForReadData). This
function is used by ChunkKeyHandler.
