Chrome's clipboard expiration time can be set via "field trial".
One Chrome iOS Widget also reads the clipboard, but iOS Widget can't read directly "field trial" values, so right now the clipboard expiration time for that iOS Widget is hard-coded (to 1 hour).

Ideally, the iOS Widget's and Chrome's clipboard expiration time should be kept in sync.

Our options are:
A/ Have Chrome iOS pass the expiration time to the iOS Widget.
B/ Wait and remove the field trial once we have settled on one constant, and use that constant for the iOS Widget.
C/ Do nothing.
