Feature request: timeout for cookies

[arifin-chemist89]

This is one of the follow up of the authentication issue discussed in https://discourse.holoviz.org/t/tips-guide-on-creating-a-simple-username-password-auth-for-panel-app/2582.

Is your feature request related to a problem? Please describe.

I am using authentication to keep my app secure. However, since there is no expiration of the cookies in Panel, the user could directly access the app and bypass the login page after it is authenticated.

Describe the solution you'd like

It is better to have configurable cookies timeout in Panel.

Describe alternatives you've considered

Another way is to clear cookies on_session_destroyed
