Joachim Wiberg 6521de28e7 confd: check for control-plane-protocol before migration
Refactor 0f9d429 to first check if the .cfg file has any routing
protocol active before converting the type's value.

This fixes a regression in the release cycle that otherwise would
cause a fresh startup-config, created from a plain factory-config
from v24.08, to be converted to an empty file.

Inspired by this fix, the same mitigation, albeit highyl unlikely,
has been applied to the v1.0 user shell type migration.

Joachim Wiberg 35eeae55f4 confd: skip veth peer also when deleting interfaces
When adding interfaces over NETCONF/RESTCONF, confd has a check to
ensure the peer end is skipped, since creating one end also create
the other.

This patch adds the corresponding skip when deleting a VETH pair.

Joachim Wiberg dd3f1c39d1 confd: expand route info in operational data
- Enable OSPF route metrics in RIB, only defined for OSPF
 - Enable 'active' route flag for RIB, same as 'selected >' in FRR
 - Enable 'last-updated' route field for RIB, used for uptime
 - Augment route in RIB with 'installed' flag, same as 'FIB *' in FRR

The CLI "show ip route" command has been updated accordingly.  The
classic Cisco style output has been kept instead of separating the
routes into Active and Backup, as discussed previously.  Because
when inspecting large route sets you want to compare same prefix
vs distance/metric to understand why a certain route is selected.

Joachim Wiberg 2063c94f42 confd: drop deviation for /if:interfaces-state
Not the most obvious patch, but let me explain -- there will always be a
conflict betweem usability and "maintainability".  The ietf-interfaces
yang model already declares /interfaces-state as deprecated, so we don't
really need to add a deviation 'not-supported', for usability, however,
it may be useful since the deviation helps cut out that tree completely.

While working with ietf-routing and our companion models, I found that
since it relies on ietf-interfaces, it also breaks the reload/reimport
of infix-routing while developing extensions/changes:

  $ lint.sh -f tree ieee802-* iana-if-type@2023-01-26.yang \

	    ietf-ospf@2022-10-19.yang \

The only way to change/update models for a given build is to either, a)
surgically remove offending models from output/target/, then reinstall
all dependencies and hope it works better, or b) rebuild from distclean.
In most cases you end up with alternative b).

Joachim Wiberg fa6851caa6 board/common: set DHCP and ZeroConf routes using Frr/staticd
This patch changes the way Infix DHCP and ZerocConf clients set their
routes in the system.  Instead of setting them directly in the kernel
we ask FRR staticd to set them for us.

The reason for this change is to be able to override routes from these
protocols with locally set static routes.  The routes are now set with
a distance of 5 and 254, respectively, while static routes by default
have a distance of 1.  In contrast, kernel routes are always treated
by Frr as distance 0, i.e., they are preferred over static routes.

Finally, this patch drops the use of Linux legacy interface aliases, or
colon interfaces, in an effort to reduce confusion for end users.  This
may give some odd results if using older tools like ifconfig, so we
recommend using 'show interfaces' or 'ipb a' instead.

Joachim Wiberg fd8826c3f1 confd: initialize sysrepo startup datastore at boot
Since /etc is not retained across reboots, the sysrepo startup datastore
is not used to bootstrap the Infix.  Instead, /cfg/startup-config.cfg is
used and loaded directly to the running datastore.

For some use-cases when operating directly on sysrepo this causes a lot
of confusion because startup == factory ds until any user calls the CLI
command `copy running-config startup-confg`.

This patch fixes this initial "glitch" by loading the starup datastore
at boot on successful loading of startup-config to unning.

To prevent any unintentional "auto-save" of, e.g., failure-config to
startup-config, we make confd aware of this "sync" operation during
bootstap.

Joachim Wiberg db136bce32 Fix container upgrade regression
In 0edc2d5 and afbe5ca, just prior to v24.06.0-rc1, support for deleting
containers in the background was added.  However, this also broke support
for upgrading containers.

In afbe5ca the start script for containers was renamed from NAME.sh to
S01-NAME.sh, but the container wrapper script's upgrade command was not
updated.  Neither was the cleanup and post-hook callbacks in confd!  So
when a container had been added to the system, the cleanup callback just
simply deleted the script, preventing it from being recreated at ugprade

This patch fixes the container identification code and also refactors
the execd code to ensure that kill scripts (for deleting in background)
and start scripts are run in the proper order *and* ensuring that execd
also does not accidentally remove the container start script.

Some cosmetic changes to the output at upgrade have also been added.
