Improve messaging when clicking links on timedout session

[Lin Hua Cheng]

When the session timedout, clicking links on the panel displays "An error occured. Please try again.".

Clicking the link multiple times would not help. we should provide a better messaging or redirect the user to the login page.

How can one reproduce this bug? I tried to click some panel links and some tab and table links. Clicking always redirect me to the login page.

Try clicking on links that open a pop-up, like clicking the Edit actions.

The user just encounters and error on the screen that has nothing to do with the real problem. This is going to require a change as to how modals handle errors.

Session timeout has to result in login redirection rather than proper messaging. Refer https://bugs.launchpad.net/horizon/+bug/1214812

This has been vastly improved in H3, marking the bug as completed.
