Description

Consider the following code to start the HTTPS server:

route := gin.New()
route.RunTLS(addr, tlsCert, tlsKey)

Is there any way to reload the TLS cert? I have looked through the doc and searched the internet but failed to find the answer.

Is it possible to have something like this to reload the cert when cert is changed

route.reloadTLS(tlsCert, tlsKey)

I can contribute if it is reasonable and not hard to implement
