Contains 2 testcases. The first does a basic configuration/connectivity.
The second testcase initiates a shortcut through the primary NHS,
verifies shortcut routes are installed. Primary NHS interface brought
down and verify that the shortcut is not impacted. Finally verify that
after the shortcut expires, it is able to be re-established via a backup
NHS.

Locally this test would occassionally fail for me
because the connected route the sharp route being
installed has not fully come up yet due to heavy
load and start up slowness. Add a bit of code
to look for the problem and make sure it doesn't
happen.

Current command (bundled two into one) is absolutely wrong.
When you configure TCP session with the source, the command thinks, that
it's a SSH session with a username.
It's much better to split this into two separate commands where it's much
easier to do the changes in the future (if more options comes in).
Yes, this is a breaking change, but there is no other proper way to overcome
this.
Bonus note how it looks, which also can lead to crashes (due to port 0x0):
```
(gdb) p *cache->tr_config.ssh_config
$11 = {host = 0x5555562f9cd0 "1.1.1.1", port = 0, bindaddr = 0x0,
username = 0x55555629ad00 "",
server_hostkey_path = 0x7ffff53667a0 <rpki_create_socket> "Uf\017\357\300H\211\345AWAVAUATSH\201", <incomplete sequence \354\230>, client_privkey_path = 0x0,
data = 0x0, new_socket = 0x51, connect_timeout = 4143762592,
password = 0x7ffff6fccca0 <main_arena+96> "\300\"0VUU"}
(gdb) p *cache->tr_config.tcp_config

Leaked route from the l3VRF are installed with the loopback as the
nexthop interface instead of the real interface.
> B>* 10.0.0.0/30 [20/0] is directly connected, lo (vrf default), weight 1, 00:21:01
Routing of packet from a L3VRF to the default L3VRF destined to a leak
prefix fails because of the default routing rules on Linux.
> 0: from all lookup local
> 1000: from all lookup [l3mdev-table]
> 32766: from all lookup main
> 32767: from all lookup default
When the packet is received in the loopback interface, the local rules
are checked without match, then the l3mdev-table says to route to the
loopback. A routing loop occurs (TTL is decreasing).

Do not set the lo interface as a nexthop interface. Keep the real
interface where possible.

- Add separate get, get-config, get-state operations to query command, as
well as switching default output to JSON.
- Add an `--xml` to change the output format.
- move printss to logging.debug so output is a machine parseable result.

Similarly to recently fixed 'show ip[v6] prefix-list ...' - PR#15750,
json output is not valid for 'show ip[v6] access-list ... json' commands,
as it goes through all the running daemons and for each one it calls
'filter_show' creating a new json object. To aggreagate the output
and create a valid json that can later be parsed, the commands were
moved to vtysh and formatted accordingly

When testing SNMP service on FRR, the following error message may
appear on some distros.
> # snmpwalk -v2c -c public .1.3.6 1.1.1.1 <OID>
> Bad operator (INTEGER): At line 73 in /usr/share/snmp/mibs/ietf/SNMPv2-PDU
> [..then result ..]
>
The error message is due to the /etc/snmp/snmp.conf file. By default, this
file is used by both snmp server and client side. The net-snmp MIB parsing
routing loads MIBS, to bind oids with the naming scheme used by the MIBS.
> # cat /etc/frr/snmp.conf
> [snmp]
> mibs +ALL
>
A potential fix would consist in modifying the SNMPv2-PDU.mib file: the
problem is known on ubuntu distros, as the snmp-mibs-downloader package
has not updated the SNMPv2-PDU.mib file.
The choice is done to not modify the original distro where the test is run
on. Fix the topotests by ignoring the 'SNMPv2-PDU line 73" error message, and
keep the other error messages that may happen, for instance, when an
unknown oid name value is requested.
