VRRP model does not support authentication

[fatpelt]

Enhancement summary

According to the documentation the VRRP model on ethernet_interfaces (among others) does not support vrrp authentication tokens

Which component of AVD is impacted

eos_cli_config_gen

Use case example

Converting the following hsrp config to vrrp will fail because we don't have auth:

standby version 2
standby 9 ip 1.1.1.1
standby 9 priority 110
standby 9 preempt
standby 9 authentication someAuthenticationToken
standby 9 name hsrp-v4-v277-9

the EOS vrrp conversion of this would be:

vrrp 9 ipv4 version 2
vrrp 9 ipv4 1.1.1.1
vrrp 9 priority-level 110
vrrp 9 preempt
vrrp 9 peer authentication text someAuthenticationToken
vrrp 9 session description hsrp-v4-v277-9

Describe the solution you would like

maybe something like:

vrrp_ids:
  - id: <int; required; unique>
    authentication:
      protocol: <str; 0|7|8a|ietf-md5>
      keystring: <str>

Given the following CLI:

eos-1(config-if-Et1)#vrrp 10 peer authentication 0 test
eos-1(config-if-Et1)#show active

interface Ethernet1
   vrrp 10 peer authentication text 7 qiREoEyZq2o=

eos-1(config-if-Et1)#vrrp 10 peer authentication ietf-md5 key-string 0 test
eos-1(config-if-Et1)#show active

interface Ethernet1
   vrrp 10 peer authentication ietf-md5 key-string 7 qiREoEyZq2o=

I would suggest the following data model:

vrrp_ids:
  - id: <int; required; unique>
    peer_authentication:
      text: <str>
      ietf_md5_key_string: <str>      
      password_type: <"0", "7", "8a", default=7>

re the model, text and ietf_md5_key_string would be mutually exclusive. Let the md5 take precedence.

[ClausHolbechArista]

Another model suggestion (more consistent with other areas):

vrrp_ids:
  - id: <int; required; unique>
    peer_authentication:
      mode: <str; "text" | "ietf-md5"; required>
      key: <str; required>
      key_type: <"0", "7", "8a", default=7>
