This reverts commit 6ff21acf4c4d4ef08bbef419ba582cade4da8da7.
This commit has broken config options with colons in them.
The following is a sample configuration that no longer works:
[[post-config|/etc/neutron/plugins/ml2/ml2_conf.ini]]
[restproxy]
server_ssl=False
servers=10.211.1.9:80
server_ssl=False
With the above config and the code present that this reverts,
the 'servers' option will come out blank.
