Current example is:
`echo "reload" | socat /var/run/haproxy-master.sock`
it will cause socat error:
`exactly 2 addresses required (there are 1); use option "-h" for help`
Correct working command is:
`echo "reload" | socat /var/run/haproxy-master.sock stdin`
Example:
- $ echo "reload" | socat /var/run/haproxy-master.sock
+ $ echo "reload" | socat /var/run/haproxy-master.sock stdin
Note that a reload will close the connection to the master CLI.
