Review comment:
       But, the code and the configs that are being added past this if check 
all seem to be somehow related to remaps though?

   I'd say this is more of what we _want_ to support though. It seems 
reasonable that we'd only enable remap reloads, if there was a valid remap 
during start up.
   
   ```  REC_RegisterConfigUpdateFunc("proxy.config.url_remap.filename", 
url_rewrite_CB, (void *)FILE_CHANGED);
     REC_RegisterConfigUpdateFunc("proxy.config.proxy_name", url_rewrite_CB, 
(void *)TSNAME_CHANGED);
     REC_RegisterConfigUpdateFunc("proxy.config.reverse_proxy.enabled", 
url_rewrite_CB, (void *)REVERSE_CHANGED);
     REC_RegisterConfigUpdateFunc("proxy.config.http.referer_default_redirect", 
url_rewrite_CB, (void *)HTTP_DEFAULT_REDIRECT_CHANGED);
   
     // Hold at least one lease, until we reload the configuration
     rewrite_table->acquire();```
