Subject: [PATCH 21/31] MINOR: server: Make 'default-server' support 'observe'
keyword.
X-Bogosity: Ham, tests=bogofilter, spamicity=0.000000, version=1.2.4
Before this path, 'observe' setting was only supported by 'server' directives.
This patch makes 'default-server' directives also support 'observe' setting.
Should not break anything.
