You dug yourself in a hole here by changing the default URL as we saw
in the debug output:
> *# Environment url = http://10.0.100.139:%d/server-status?auto*

The plugin normally uses 127.0.0.1 to access server-status so if you
hadn't changed the URL you would have been fine. As I said, the above
sans the "Allow from 10.0.100.135" is the Apache dafault and it is
sufficient for Munin.

So don't touch the Apache config, change the plugin conf and verify with
munin-debug. When it works, restart munin-node.
