Rank (Obsolete): 9223372036854775807

 Description   

Add statistics to measure the average/maximum time spent in the LNet/LNDs for the following cases:
1. Average/maximum time for receiving an LNet ACK/REPLY
2. Average/maximum time messages are queued on the LND outgoing queues
3. Average/maximum time LND transmits remain active (IE awaiting completion, either via response or a completion event).

Add ability to extract these values from lnetctl.
