New Constaint Shortest Path First algorithm has been introduce in FRR library.
Add a new 'show sharp cspf' command as example of how to use these
CSPF algorithm.

As this comment says. ZEBRA_FLAG_XXX should not have been used.
To communicate SRv6 Route Information. A simple Nexthop Flag would
have been sufficient for SRv6 information. And I fixed the whole
thing that way.

The "show sharp segment-routing srv6" command was a
json output command, but it did not follow the common
practice of the other commands.
It follows the review and outputs the json format by
using the json keyword. Otherwise, it produces human
readable output.

We can install seg6 routes from shapd cli.
This is for the behaviour test(topotest) to ensure
SRv6 ZAPI is working fine.

In this patch, we can install seg6local routes from shapd cli. New sub
command "sharp install route $PREFIX nexthop-seg6local" is added to
install seg6local routes via ZEBRA_ROUTE_ADD. This is for the behaviour
test(topotest) to ensure SRv6 ZAPI is working fine.
NEW-CLI:
sharp install routes 1::1 nexthop-seg6local dum0 End 1
sharp install routes 2::1 nexthop-seg6local dum0 End_X 2001::1 1
sharp install routes 3::1 nexthop-seg6local dum0 End_T 10 1
sharp install routes 4::1 nexthop-seg6local dum0 End_DX4 10.0.0.1 1
SRv6 routes are installed as NEXTHOP_IFINDEX routes because of seg6local
specification. seg6local routes depends the output device status instead
of routing-nexthop.
FYI:
In seg6local implementation, kernel don't care RTA_OIF on the nexthop
deeply but some requirement are exist as follow.
(a) DEV isn't loopback interface
(b) DEV's ipv6 status is enabled
(c) DEV's enslaving status is the same with target-route

current route addition mechanism on shaprd support only ipv4/v6 nexthop
routes simply. so It doesn't need to ensure flags of zapi_routes.
Then when we want to configure more complicated routing feature (like a
srv6), we will want to control flags of zapi_route. In this patch, it
will supports to configure flags of zapi_route when sharpd calls
ZEBRA_ROUTE_ADD.

The remove lsp command was using the wrong list of route
protocols - use the ZEBRA list, same as the other clis.

Add new feature and commands to sharpd in order to collect Traffic Engineering
Database information from an IGP (OSPF or IS-IS) though the ZAPI Opaque
Message and the support of the Link State Library.
This feature serves as an example of how to code a Traffic Engineering
Database consumer and tests the mechanism.

Initial changes to support a nexthop with multiple backups. Lib
changes to hold a small array in each primary, zapi message
changes to support sending multiple backups, and daemon
changes to show commands to support multiple backups. The config
input for multiple backup indices is not present here.

With the command using STR_SHARP, the sharp daemon is not allowed
to use it's own routes for label modification. Switching over
to STR_ZEBRA allows the sharp daemon to modify labels on any
route in the system, since there are no `ROUTE_ZEBRA` types.

This just generates log messages in bulk for testing logging backend
performance. It's in sharpd so the full "context" of being in a daemon
is available (e.g. different logging configs, parallel load in the main
thread.)

First round of support for exercising the lsp and ftn paths
using sharpd. This supports lsp-only, and binding to
ipv4 prefix. Also use the common lib nexthop-to-zapi
helper api instead of sharpd's open-coded version.

Current autocompletion works only for simple "vrf NAME" case.
This commit expands it also for the following cases:
- "nexthop-vrf NAME" in staticd
- usage of $varname in many daemons
All daemons are updated to use single varname "$vrf_name".

Instead of defaulting the import-check to a /32
allow the tester to specify any prefix that they want
when doing an import-check.
Test:
donna.cumulusnetworks.com# sharp watch import
A.B.C.D/M The v4 prefix for import check to watch
X:X::X:X/M The v6 prefix to signal for watching
