Remove flash_msg_div from retire screen

[mzazrivec]

The div would produce warnings about duplicate ids.

@mzazrivec : if you put it like this, it's hard to review, unless I do all the research myself :-(

Where is it included from? Is it ever rendered separately? Where is it updated from?

@martinpovolny The thing here is that the flash_msg_div in that screen is not needed. As far as I can tell, we never render flashes when we're in the retirement screen. We only render flash messages after the retirement form submission, i.e. either in the explorer screen or the service / vm / orch. stack summary screen.
