 Issue 298759  has been merged into this issue.

 Issue 738306  has been merged into this issue.

Let's just commit the action as we do today, and use toasts to handle the confirmation and undo.

Toasts already exist in MD-Bookmarks and should generally be applied to all areas of Settings that deal with sensitive information, such as Site Details. 

https://docs.google.com/presentation/d/1GILSCx1IFUHC8WHyrP2Iymjq9_swPw4xB5D_2PbiBcE/edit#slide=id.g24381d27bb_3_37

I'd imagine just 1 toast (not 2 as in passwords.google.com) in the bottom left, reading:

[ Password deleted             UNDO  ]

The same timing logic and color styling used in Bookmarks is applicable here as well. 

 Issue 755469  has been merged into this issue.

+tost_manager.html authors, tsergeant@, calamity@

To summarize some discussion in the CLs and among the Settings team, we should move bookmarks-toast-manager from md_bookmarks/ to a shared location and use it in Settings.

The correct location for the shared element is ui/webui/resources/elements/ because 'cr-toast-manager' is a single element that should not require any strings.

The current implementation includes an 'Undo' button, but that should either be part of the toast <content>, or a more generic 'button-label' property if we think 'toast' will always include a button (which seems reasonable to assume until / unless a scenario comes up where we don't need a button).

To make sure it's not forgotten: we need to have keyboard support for undo CTRL + Z (COMMAND + Z on mac) for accessibility.

Timeouts on toast may not last long enough for someone with mobility issues or someone who is trying to use a screen reader. 

If the toast will always have a button like Steven suggested in #10, then we should make the toast handle the keyboard shortcut so it's not forgotten.

Implement "Undo Delete Password" in Settings Page

This change implements an UNDO toast following a deletion of a saved password or
password exception entry. It is similar in looks and functionality to the
already exising UNDO toast for MD Bookmarks.
