Component(s) name

l3ls role

templates:

• eos_l3ls_evpn/templates/evpn-fabric-l3leaf-yml.j2
• eos_l3ls_evpn/templates/evpn-fabric-l2leaf-yml.j2
• eos_l3ls_evpn/templates/fabric/mlag/leaf-mlag-configuration.j2

Proposed changes

Added a var dual_primary_detection (default is true) to l3leaf/defaults and l3leaf/node_groups/group and l2leaf/defaults and l2leaf/node_groups/group.

This is consumed by l3ls role to generate appropriate structured config

How to test

run the l3ls role with this sort of examples (dual_primary_detection: false/true at diff levels)
