Feat(eos_designs): Allow VLAN Aware Bundles even if common evpn_vlan_aware_bundles is false

[bjmeuer]

Change Summary

If for a l2vlan or svi in network_services a "evpn_vlan_bundle" is defined the common setting of "evpn_vlan_aware_bundle" is ignored. Meaning even if evpn_vlan_aware_bundle:false a vlan aware bundle will be used for a l2vlan/svi when the "evpn_vlan_bundle" is defined for it.

Please also update the doc for the root evpn bundle key, since it's behavior is now to force evpn vlan bundle for all VLANs. And maybe hint that if they only wish to enable bundles for some vlans they can be set with the new(er) key.

Tested on a POC inventory with bundles. Working well and there is a clear improvement compared to 4.7.1 behavior.
