protocol/server: make listen backlog value as configurable
problem:
When we call listen from protocol/server, we are giving a
hard coded valie of 10 if it is not manually given.
With multiplexing, especially when glusterd restarts all
clients may try to connect to the server at a time.
Which will result in overflowing the queue, and kernel
will complain about the errors.
Solution:
This patch will introduce a volume set command to make backlog
value as a configurable. This patch also changes the default
values for backlog from 10 to 128. This changes is only applicable
for sockets listening from protocol.
Example:
gluster volume set <volname> transport.listen-backlog 1024
Note: 1 Brick has to be restarted to get this value in effect
2 This changes won't be reflected in glusterd, or other
xlators which calls listen. If you need, you have to
add this option to the volfile.
