cs_loadbalancer_rule_member fails when rules have similar names

[onitake]

I'm hitting the error More than one rule having name lb_group_worker-http. Please pass 'ip_address' as well., even though I'm already passing the IP address and there is only a single rule with this name. There is a second loadbalancer rule with a similar name, however: lb_group_worker-https

Other rules with more unique names (like lb_group_master) work fine.

It looks like the CloudStack API does not match rule names exactly, as it should.
