Documented endpoint failure when HTTP authentication disabled.
The `/reserve` and `/unreserve` endpoints currently do not work when
HTTP authentication is disabled. To enable correct behavior, the
`principal` field of `ReservationInfo` is being migrated from `required`
to `optional`. This patch documents this behavior of these endpoints.

Changed 'ReservationInfo.principal' from required to optional.
In order to allow dynamic reservation without a principal, this field is
being changed to optional. However, the current patch alters the master
to invalidate any reserve operations that do not set this field. After a
deprecation cycle, the master will allow the field to be unset.

>
> With the addition of HTTP endpoints for {{/reserve}} and {{/unreserve}}, it
> is now desirable to allow dynamic reservations without a principal, in the
> case where HTTP authentication is disabled. To allow for this, we will change
> the {{principal}} field in {{ReservationInfo}} from required to optional. For
> backwards-compatibility, however, the master should currently invalidate any
> {{ReservationInfo}} messages that do not have this field set.
