Aesthetic changes to the proxy configuration log format....

Aesthetic changes to the proxy configuration log format.

Also in this change, I stop brodacasting the proxy settings changes to LOG(INFO) --- This is because navigating to "view-net-internal:proxyservice.config" offers a better solution, so no point polluting the log file.

Note that the format change is intended to make the string more succint and human readable. For example, here is a before and after comparison:

------------
New version:
------------

Automatic settings:
  Auto-detect: No
  Custom PAC script: [None]
Manual settings:
  Proxy server: [None]
  Bypass list: [None]
  Bypass local names: No

------------
Old version:
------------

{
  auto_detect: 0
  pac_url: 
  proxy_rules:
  {
    type: TYPE_NO_RULES
    single_proxy: 
    proxy_for_http: 
    proxy_for_https: 
    proxy_for_ftp: 
    socks_proxy: 
  }
  proxy_bypass_local_names: 0
  proxy_bypass_list:
  id: 1
}
