Adding operation type support - to include "remoteservice"

[gautambaghel]

resource "apigee_product" "apigee_product" {
  name               = "httpbin"
  display_name  = "httpbin"
  auto_approval_type = true
  description        = "A httpbin product"
  environments = [
    "test"
  ]
  attributes = {
    access = "public"
  }
  operation {
    api_source = "httpbin.default.svc.cluster.local"
    path       = "/"
    methods    = ["GET", "PATCH", "POST", "PUT", "DELETE", "HEAD", "CONNECT", "OPTIONS", "TRACE"]
  }
  operation_config_type = "remoteservice" # New setting -- completely optional, defaults to proxy
}

• OperationGroup settings allow for remote service and proxy as setting documentation

This is very useful for working with the remote service envoy plugin with Apigee

• remote-service-envoy

Testing

I've tested it with setting the operation_config_type variable as follows

• keeping empty or not giving any value --> defaults to operationConfigType as proxy
• as "remoteservice" --> correctly sets the httpbin product operationConfigType as remoteservice
• as "random" --> throws an error "Invalid value for operation_config_type, must be either 'proxy' or 'remoteservice'"
