master: make volume capacity reservation timeout configurable (#11426) (#11497)

* master: make volume capacity reservation timeout configurable (#11426)

* master: expire reservations on reads, fix int timeout units

- AvailableSpaceForReservation now expires reservations too: a node that
  is full of reservations is filtered out before TryReserveCapacity can
  clean them, which stranded expired capacity indefinitely.
- Drop TryReserveCapacityWithTimeout: a per-call timeout lets one caller
  expire another's live reservations, and the Node interface stays
  stable for implementations outside this tree.
- parseReservationTimeout no longer routes integer values through
  GetDuration, which read them as nanoseconds; bare numbers are
  seconds. The 5m fallback is now the shared DefaultReservationTimeout.
