In ticket #3291, the function "CountClient" was added. It counts the number of client base on the number of saved client. However, there are some client wasn't saved yet because its initialization is in progress.

log: Update counting log client [#3313]

A log client is not saved to the client list until the log agent receives
the response from log director for initialization. Therefore, the size of
client list doesn't represent the number of clients in the system. Solution
is to count the log clients base on the user counter.
