MINOR: peers: Add "log" directive to "peers" section.

This patch is easy to review: let's call parse_logsrv() function to parse
"log" directive as this is already for other sections for proxies.
This enable us to log incoming TCP connections for the listeners for "peers"
sections.

Update the documentation for "peers" section.
