core: support flag "preserve-external-ip" for Reapply() call
Reapply() is supposed to make sure that the system (the interface)
is configured as indicated by the applied-connection. That means,
it will remove/add configuration to make the system match the requested
configuration.

Add a flag "preserve-external-ip" which relaxes this. During reapply,
IP addresses/routes that exist on the interface and which are not known
(or added) by NetworkManager will be left alone.

This will be used by nm-cloud-setup, so that it can reconfigure the
interface in a less destructive way, which does not conflict with
external `ip addr/route` calls.

Note that the previous commit just adds "VersionInfo" and the
possibility to expose capabilities (patch-level). This is not used
for the new reapply flag, because, while we might backport the
reapply flag, we won't backport the "VersionInfo" property. Exposing
new capabilities via the "VersionInfo" property will only become useful
in the future, where we can backport a capability to older NM versions
(but those that have "VersionInfo" too).

Udi:
Operating-system specific transient device hardware identifier. This is an
opaque string representing the underlying hardware for the device, and
shouldn't be used to keep track of individual devices. For some device
types (Bluetooth, Modems) it is an identifier used by the hardware service
(ie bluez or ModemManager) to refer to that device, and client programs
use it get additional information from those services which NM does not
provide. The Udi is not guaranteed to be consistent across reboots or
hotplugs of the hardware. If you're looking for a way to uniquely track
each device in your application, use the object path. If you're looking
for a way to track a specific piece of hardware across reboot or hotplug,
use a MAC address or USB serial number.
Note that non-UTF-8 characters are backslash escaped. Use g_strcompress()
to obtain the true (non-UTF-8) string.

Reapply:
@connection: The optional connection settings that will be reapplied on the device. If empty, the currently active settings-connection will be used. The connection cannot arbitrarily differ from the current applied-connection otherwise the call will fail. Only certain changes are supported, like adding or removing IP addresses.
@version_id: If non-zero, the current version id of the applied-connection must match. The current version id can be retrieved via GetAppliedConnection. This optional argument allows to catch concurrent modifications between the GetAppliedConnection call and Reapply.
@flags: Flags which would modify the behavior of the Reapply call. Invalid flags are rejected.
Attempts to update the configuration of a device without deactivating it.
NetworkManager has the concept of connections, which are profiles that
contain the configuration for a networking device. Those connections are
exposed via D-Bus as individual objects that can be created, modified and
deleted. When activating such a settings-connection on a device, the
settings-connection is cloned to become an applied-connection and used to
configure the device (see GetAppliedConnection). Subsequent modification
of the settings-connection don't propagate automatically to the device's
applied-connection (with exception of the firewall-zone and the metered
property). For the changes to take effect, you can either re-activate the
settings-connection, or call Reapply. The Reapply call allows you to
directly update the applied-connection and reconfigure the device. Reapply
can also be useful if the currently applied-connection is equal to the
connection that is about to be reapplied. This allows to reconfigure the
device and revert external changes like removing or adding an IP address
(which NetworkManager doesn't revert automatically because it is assumed
that the user made these changes intentionally outside of NetworkManager).
Reapply can make the applied-connection different from the
settings-connection, just like updating the settings-connection can make
them different.
Since 1.42, "preserve-external-ip" flag (0x1) is supported to not remove
externally added IP addresses and routes on the device during reapply.

GetAppliedConnection:
@flags: Flags which would modify the behavior of the GetAppliedConnection call. There are no flags defined currently and the users should use the value of 0.
@connection: The effective connection settings that the connection has currently applied.
@version_id: The version-id of the currently applied connection. This can be specified during Reapply to avoid races where you first fetch the applied connection, modify it and try to reapply it. If the applied connection is modified in the meantime, the version_id gets incremented and Reapply will fail.
Get the currently applied connection on the device. This is a snapshot of
the last activated connection on the device, that is the configuration
that is currently applied on the device. Usually this is the same as
GetSettings of the referenced settings connection. However, it can differ
if the settings connection was subsequently modified or the applied
connection was modified by Reapply. The applied connection is set when
activating a device or when calling Reapply.
