modified:   doc/sphinx/arm/dhcp6-srv.rst

[#3348] Update docs about subnet/pool selection

The change that would have helped the reporter:
- Add paragraph explaining that out-of-network guarded subnets need
  EGRL enabled in order for those guards to properly select subnets.

Other important changes:
- Define class guards. They are referenced in some places in the ARM,
  but never defined.
- Move "unreserved_class" guards before "reserved_class" guards so that
  it is clear that a pool or a subnet is skipped and the allocator takes
  a different path than usual, assumin an iterative allocator.
- Add unguarded subnets and pools and explain that those are available
  to both reserved and unreserved clients.
- Add paragraph explaining that in-subnet reservations don't work when
  the subnet belongs to a shared network.
- Add paragraph explaining that for a subnet to be selected, when
  choosing to do the selection via pools, as the example is structured,
  all of the pools inside the subnets desired to be skipped or selected
  need to be guarded.
- Add missing name to shared network in the JSON config examples.

Less important changes:
- Remove comments about reservation settings. Some were forgotten to be
  removed since new reservation flags are added, but overall they don't
  need to be explained because these sections are not focused on reservations.
- Add curly brackets to make the whole JSON valid and add code-block:: json
  and reindent.

  allocations are on constructor and on clear().
