parameter cleanup of modified output file not working as expected

[rjhicks41]

parameters that are removed from json template do not get removed from an updated parameter file.

to recreate:

run cf_parameter_generator
cf_parameter_generator -f input.json -o output.json

edit input.json to change the name of a pre-existing parameter
"ELBListenersLoadBalancerPort": { "Description": "Specifies the external load balancer port number", "Type": "String" },

changes to:

"ELBListenersLoadBalancerPortHTTP": { "Description": "Specifies the external load balancer port number for HTTP connections", "Type": "String" },

re-run cf_parameter_generator:
cf_parameter_generator -f input.json -o output.json

view output.json and you'll find this:
{ "ParameterKey": "ELBListenersLoadBalancerPort", "ParameterValue": "80" }, { "ParameterKey": "ELBListenersLoadBalancerPortHTTP", "ParameterValue": "Type: String" }, { "ParameterKey": "ELBListenersLoadBalancerPortHTTPS", "ParameterValue": "Type: String" },

when you were looking for this:
{ "ParameterKey": "ELBListenersLoadBalancerPortHTTP", "ParameterValue": "Type: String" }, { "ParameterKey": "ELBListenersLoadBalancerPortHTTPS", "ParameterValue": "Type: String" },

ugh...my markdown fu is not json compatible. :)

If you include -r it will remove old entries. But your comments make me think about the case where someone renames something. It would be better to rename the parameter as well, but that's harder to detect. I'll think about this and ways that it can be detected and updated.
