Currently,the action_reset_password is only available at form view
of res.user under the 'Send reset password instructions' button.
The purpose of this task is to allow admins to send password reset instructions
to multiple users at once from list view.
In this commit, we make action_reset_password available in the action menu of
list view with label 'Send password reset instructions' and relabel the form
view button to 'Send password reset instructions'.
As when the user is created at that time it will send the 'accept invitation'
mail so here from list view we will always send the 'change password' mail even
user is never connected(state='new').
