Make it harder to delete issuables accidentally

Previously submitting a DELETE request to an issuable URL would be
enough to destroy it, but this should require human confirmation.  We
now require that the `destroy_confirm` parameter is set to a truthy
value before this can complete.

In addition, we log a Sentry error if a deletion arrived without
confirmation.
