Prevent reading request and response body

[fredmaggiowski]

Is your feature request related to a problem? Please describe

The possibility to run policy over the request/response body is a nice feature, however it's not always useful but still rönd loads the whole body is the content type is supported.

When dealing with large request bodies this may lead to:

• adding latency
• memory issues (e.g. we have a pod being killed from time to time for going OOM)

Describe the solution you'd like

I'd like to have some flag in the OAS extension that can let me disable the body reading feature

{
   "x-rond": {
      "requestFlow": {
         "policyName": "policy_to_be_executed_BEFORE_API_invocation",
         "preventRequestBodyLoad": true|false. // disable only for request
       },
        "responseFlow": {
         "policyName": "policy_to_be_executed_AFTER_API_invocation",
         "preventRequestBodyLoad": true|false // disable only for response
       },
       "options": {
         "enableResourcePermissionsMapOptimization": false,
         "ignoreTrailingSlash": false,
         "preventRequestBodyLoad": true|false  // disable for both request and response
      }
   }
}

Describe alternatives you've considered

Increasing memory: no thanks...

Additional context

Rönd version used: 1.10.1
OAS support could be implemented in v2 only (x-rond)
