This new daemon manages Segment-Routing Traffic-Engineering
(SR-TE) Policies and installs them into zebra. It provides
the usual yang support and vtysh commands to define or change
SR-TE Policies.
In a nutshell SR-TE Policies provide the possibility to steer
traffic through a (possibly dynamic) list of Segment Routing
segments to the endpoint of the policy. This list of segments
is part of a Candidate Path which again belongs to the SR-TE
Policy. SR-TE Policies are uniquely identified by their color
and endpoint. The color can be used to e.g. match BGP
communities on incoming traffic.
There can be multiple Candidate Paths for a single
policy, the active Candidate Path is chosen according to
certain conditions of which the most important is its
preference. Candidate Paths can be explicit (fixed list of
segments) or dynamic (list of segment comes from e.g. PCEP, see
below).
Configuration example:
segment-routing
traffic-eng
segment-list SL
index 10 mpls label 1111
index 20 mpls label 2222
!
policy color 4 endpoint 10.10.10.4
name POL4
binding-sid 104
candidate-path preference 100 name exp explicit segment-list SL
candidate-path preference 200 name dyn dynamic
!
!
!
There is an important connection between dynamic Candidate
Paths and the overall topic of Path Computation. Later on for
pathd a dynamic module will be introduced that is capable
of communicating via the PCEP protocol with a PCE (Path
Computation Element) which again is capable of calculating
paths according to its local TED (Traffic Engineering Database).
This dynamic module will be able to inject the mentioned
dynamic Candidate Paths into pathd based on calculated paths
from a PCE.

The test_bgp_multi_vrf_topo2.py script had a bunch
of places where it would change an interface status
or add delete routes that would affect bgp convergence
but it was never ensuring that convergence had happened
before the test verified the bgp rib. I believe this
was leading to many intermittant ci failures in
testing for other PR's to be accepted. Modify
the code to wait for bgp convergence if we just
made a change to the topology

Route recovery is tested on RT1. The focus here lies on the two
different routes to RT5. Link failures are generated by taking
down interfaces via the mininet Python interface on RT2 and RT3.
Hence routes are supposed to be adjusted to use RT3 when a link
failure happens on RT2 or vice versa.
Note that only failure recognition and recovery is "fast". BFD
does not monitor a link becoming available again.

Commit 4c75f7c773 fixed a bug in which the TI-LFA repair paths
weren't preserving the original Prefix-SID of the routes. That
commit, however, didn't update the zebra interface code to account
for backup nexthops that don't have a repair list but do have a
SR label. As a consequence, backup nexthops that didn't have any
repair label were not preserving the original Prefix-SID of the
corresponding routes. Fix this and update the TI-LFA topotest
accordingly.

Once the remote end of a connected link is shut down (or lose
its address), isisd will remove the corresponding route from its
RIB after SPF runs. A new route for the same destination should
be computed based on the local LSP, and that route by definition
doesn't have any nexthop. The problem is that, when isisd tries
to replace the old route by the new one, it fails because routes
without nexthops can't be installed. That causes the old invalid
route to remain in the RIB when it shouldn't. To fix this problem,
change the zebra interface code to uninstall a route whenever it
can't be installed (because it lacks nexthops) instead of doing
nothing in that case.
This change should fix occasional failures of the test_isis_sr_topo1
topotest.
