DOC: server: Add docs for "server" and "default-server" new "no-*" and other settings.
New boolean settings have been added to disable others. Most of them have "no-" as prefix.
"enabled" disables "disabled" setting,
"no-agent-check" disables "agent-check",
"no-backup" disables "backup",
"no-check" disables "check",
"no-check-ssl" disables "check-ssl",

Settings with arguments are now supported on "default-server" lines:
"addr", "ca-file", "ciphers", "crl-file", "crt", "cookie", "namespace", "observe",
"redir", "sni", "source", "tcp-ut" and "track".
From now on, all server "settings" including the new ones above are supported by
"default-server" except "id" which is only supported on "server" lines.
