rpcsvc: Add latency tracking for rpc programs
Added latency tracking of rpc-handling code. With this change we should be able to monitor the amount of time rpc-handling code is consuming for each of the rpc call. fixes: #1466 Change-Id: I04fc7f3b12bfa5053c0fc36885f271cb78f581cd Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
