As a Watchlist Expiry user, I want to be able to temporarily watch items via Protect, Delete, Rollback and Move, so that I can access the same feature when using such functionality.
**Acceptance Criteria:**
* Implement support for watchlist expiry drop-down in Protect, Delete, Rollback and Move
** A new label to the right (or above, depending on particular UI) of watchlist checkbox: "Watchlist time period:"
** A drop-down to the right of label (inactive by default, before box checked)
* When user checks the box to "Watch this page," the drop-down should become active
* The user should be able to select watch period via drop-down
** The drop-down has the following options:
*** Permanent (as default)
*** for 1 week
*** for 1 month
*** for 3 months
*** for 6 months
* If the page has already been watched, the behavior should be as follows:
** Drop-down should have days left as pre-selected option at top
** The selection should be written as follows: "X days left" (for example, "10 days left" or "20 days left").
* If the page has already been watched with a selected temporary time period, and the user clicks "Publish" without changing the time period selection, no changes to the watch period should be made.
* The watch period should be saved or updated, if the user makes a new time period selection.
**Visual Example:**
|{F31718243}|{F31811969}|
**Notes:**
* Rollback watchlist ability is a preference
* Protect, Delete, and move are checkboxes
* Protect is not ooui (so we can use the regular checkboxes & dropdowns)
