Problem Statement:
==================
When hello-interval is configured as 5, automatically dead interval becomes
4 times of hello i.e 20 seconds. But user wants the dead interval as
40 seconds and hello as 5 seconds. Therefore user configures it.
Now "ip ospf dead-interval 40" is not shown in "show running-config"
Therefore when user restarts the daemon, the dead interval goes back to
20 seconds and the neighbors are down.
Fix:
==================
If user configures dead-interval as 40, show it in show running config.
Fixes: #9401

The install statement was putting the daemons file at "/etc/frr" instead
of making a new directory "/etc/frr" and putting it inside there.

Alpine images have been broken for some time because libyang2 is not
available in Alpine. This patch updates our Dockerfile to build a
libyang2 APK and install it into the image to satisfy FRR's libyang2
dependency.
Unfortunately, libyang2 erroneously includes an internal header from
glibc, making it dependent on glibc to build. FRR's official Docker
images are based on Alpine, which only offers musl libc. Until libyang2
fixes this problem, the libyang2 source that is installed in this image
is a patched version that is compatible with musl libc and not an
official version.

This is to avoid breaking changes between existing deployments of
extended community for bandwidth encoding. By default FRR uses uint32
to encode bandwidth, which is not as the draft requires (IEEE floating-point).
This switch enables the required encoding per-peer.

https://datatracker.ietf.org/doc/html/draft-ietf-idr-link-bandwidth-07 says:
The bandwidth of the link is expressed as 4
octets in IEEE floating point format, units being bytes (not bits!)
per second. It is carried in the Local Administrator subfield of the
Value Field.
Before:

Extended Community (16), length: 8, Flags [OT]:

0x0000: 0004 fdeb 0001 e848
Updated routes:

0001 e848 - means 125000 (1Mbps), which is encoded incorrect.

47f4 2400 - means the same, but in floating point format.

No need to have special processing for every single node. Just always

This allows defining a CLI command like this:
`[no] some setting ![VALUE]`
with VALUE being optional for the "no" form, but required for the
positive form. It's just a `[...]` where the empty branch can only be
taken for commands starting with `no`.

Add the "metric" and "metric-type" options to the "redistribute"
command.
This is a small commit since the logic of setting the metric
value and type of external routes was already present due to the
implementation of the "default-information originate" command months
ago. This commit merely extends the "redistribute" command to
leverage that functionality.

Insist on the fact that zclient neighbor state flags are

As NHRP expects some notification of neighboring entries on GRE
interface, when a new interface notification is encountered, the
exact neighbor state flag is found. Previously, the flag passed
to the upper layer was forced to NDM_STATE which is REACHABLE,
as can be seen on below trace:
2021/08/25 10:58:39 NHRP: [QQ0NK-1H449] Netlink: new-neigh 102.1.1.1 dev gre1 lladdr 10.125.0.2 nud 0x2 cache used 1 type 5
When passing the real value, NHRP received an other value like STALE.
2021/08/25 11:28:44 NHRP: [QQ0NK-1H449] Netlink: new-neigh 102.1.1.1 dev gre1 lladdr 10.125.0.2 nud 0x4 cache used 0 type 5
This flag is important for NHRP, as it permits to monitor the link
layer of NHRP entries.
