fabricd: add option to treat dummy interfaces as loopback interfaces
Enable dummy-interfaces to be used as router-id interfaces in openfabric
networks. This allows multiple openfabric routers with different
router-ids on a single node when using IP unnumbered setup (interfaces
without IPs configured). Previously we were limited by having a single
loopback interface, allowing only one openfabric router per node.

staticd: Extend `static_zebra_release_srv6_sid` to release SRv6 uA SIDs
When removing an SRv6 uA SID, staticd should ask SRv6 SID Manager to
release the SID.
Currently, `static_zebra_release_srv6_sid` does not allow to release uA
SIDs.
This commit extends `static_zebra_release_srv6_sid` to allow staticd to

In order to configure an SRv6 uA SID in staticd, staticd should request

Currently, `static_zebra_request_srv6_sid` does not support requesting

enable staticd to request SIDs bound to the uA behavior.
yang: Extend staticd YANG model to support the SRv6 uA behavior
The SRv6 uA behavior is associated with a L3 adjacency.
This commit extends the staticd YANG model by adding two leafs
`interface` and `next-hop` under the `static-sids` container. This
extension allows us to associate an interface and a nexthop when
configuring an SRv6 uA SID.
The uA behavior is associated with an interface and the IP address of
the nexthop. However, the current SID context data structure only
includes the IP address. It lacks the interface.
This commit extends the SID context data structure by adding the
ifindex. This extension allows daemons to allocate uA SIDs with
the required interface and IP address.

Tracking this down, the crash is because the nh believes that is already
registered but lookup fails, causing this assert. Looking at the code
static_fixup_vrf is changing the vrf_id. I put a zlog_debug right
before the change of the nh vrf_id and noticed that the vrf id was
UNKNOWN. So, the code is attempting to register into zebra the nexthop
with a vrf unknown( which will be ignored ).
Modify the code in the registration process to notice that the nh is
still UNKNOWN and as such nothing should be done.

tests: Fix intermittent failures in `srv6_encap_src_addr` topotest
The `srv6_encap_src_addr` runs a vtysh command to configure the SRv6
encapsulation source address and then immediately invokes an iproute2
command to verify that zebra has set this address in the kernel. There
is no wait between the two operations and the verification is attempted
only once. If the topotest does not find the expected address it fails
immediately.
The problem is that when topotest is run on a heavyily loaded system,
it can take some time for zebra to set the address in the kernel.
In this case, when the topotest checks the kernel address right after
running the vtysh command, it doesn't find the expected address because
zebra hasn't set it yet.
This commit gives zebra some time to configure the address. It keeps to
check that the address is the expected one for about 1 minute. If after
1 minute the address is not the expected one then the test fails.
