[#1354] bump lib versions

[#1343] bumped kea version to 1.6.3

[#1343] updated copyright dates, added release entry to changelog

[#1141] ChangeLog added.

[#1124] Reversed order for v6 also

modified:
    alloc_engine.cc

# Conflicts:
# src/lib/dhcpsrv/alloc_engine.cc

[#1124] Addressed v4 code review

    Minor cleanup in alloc_engine.cc.

[#1124] Change the order of HR vs lease lookup during v4 lease allocation

src/lib/dhcpsrv/alloc_engine.cc
    AllocEngine::allocateUnreservedLease4() - rather than first testing for a
    host reservation and then looking for an existing lease, we reverse the
    order, thus worrying about HRs only if there is no existing lease.

[#1258] Fix ChangeLog to prevent CI errors

Added stable/development to the existing release dates in the changelog.

[#1258] Remove comment about thread count

Per review comments.

[#1258] spelling

[#1258] Adjusted status-get description in ARM

Removed references to passive-backup mode, removed references to 1.7.x
versions of Kea etc.

[#1258] Added ChangeLog entry for #1258

[#1258] Ported 1.7.8 changes to status-get

[#1258] Ported ha-status cmd from 1.7.3

[#1258] Ported basic status-get

The status-get command support was ported without High Availability status.

[#1155] Backported #1139 from master

This is an enhancement to client classification in DHCPv4
and DHCPv6 servers. The client classes spefified in the
host database are taken into account in evaluation of the
client classes specified within the configuration files.
This works both for the global reservations and for the
non-global reservations when the selected subnet belongs
to a shared network. It can be used to influence subnet
selection within a shared network using host reservations
or pool selection within a subnet that doesn't necessarily
belong to a shared network.
