Description

The control-plane-request-limit config entry does not support specifying parameter names in snake case format.

This commit updates the HCL and JSON examples to use the supported camel case key format.

Testing & Reproduction steps

1. Create control-plane-request-limit-snake_case.hcl with the following configuration.

   kind = "control-plane-request-limit"
   name = "global-limits"
   
   mode = "permissive"
   
   read_rate =  100
   write_rate = 100
   
   kv = {
     read_rate =  100
     write_rate = 100
   }
   
   acl = {
     read_rate =  100
     write_rate = 100
   }
   
   catalog = {
     read_rate =  100
     write_rate = 100
   }

2. Attempt to save the configuration using consul config write.

   $ consul config write control-plane-request-limit-snake_case.hcl
   Failed to decode config entry input: 8 errors occurred:
    * invalid config key "ACL.read_rate"
    * invalid config key "ACL.write_rate"
    * invalid config key "Catalog.read_rate"
    * invalid config key "Catalog.write_rate"
    * invalid config key "KV.read_rate"
    * invalid config key "KV.write_rate"
    * invalid config key "read_rate"
    * invalid config key "write_rate"
   

3. Create control-plane-request-limit-CamelCase.hcl with the following configuration.

   kind = "control-plane-request-limit"
   name = "global-limits"
   
   mode = "permissive"
   
   ReadRate =  100
   WriteRate = 100
   
   kv = {
     ReadRate =  100
     WriteRate = 100
   }
   
   acl = {
     ReadRate =  100
     WriteRate = 100
   }
   
   catalog = {
     ReadRate =  100
     WriteRate = 100
   }

4. Attempt to save the configuration using consul config write.

   $ consul config write control-plane-request-limit-CamelCase.hcl
   Config entry written: control-plane-request-limit/global-limits
