Add support for lldp tlv transmit ztp vlan under interface ethernet

Enhancement summary

EOS supports since 4.27.1.1F to announce a vlan id via lldp for inband ztp in campus lan. https://eos.arista.com/eos-4-27-1f/campus-ztp-through-vlan-advertised-from-spine-aggregation-switch/

AVD support for lldp tlv transmit ztp vlan <id> under ethernet interfaces is currently missing.

Which component of AVD is impacted

eos_cli_config_gen

Use case example

CLI config is necessary to perform inband ZTP in campus access “stack” envorinments

Describe the solution you would like

Switched Interfaces

ethernet_interfaces:  
  <Ethernet_interface_2 >:  
    lldp:  
      ztp_vlan: < ztp vlan number >

{%         if ethernet_interfaces[ethernet_interface].lldp.ztp_vlan is arista.avd.defined %}
    lldp tlv transmit ztp vlan {{ ethernet_interfaces[ethernet_interface].lldp.ztp_vlan }}
{%         endif %}

should generate:

interface Ethernet<nr>
   lldp tlv transmit ztp vlan <ztp vlan number>

Describe alternatives you have considered

current alternative is to use eos_cli unter interface ethernet
