**What I did**
Fix the Mem Leak by moving the raw pointers in type_maps to use smart pointers
**Why I did it**
```
Indirect leak of 83776 byte(s) in 476 object(s) allocated from:

What I did
Replace Neigh entries if it exists and add as state reachable during warmboot neighbor restoration.
Why I did it
During warmboot,
restore_neighbors.pyrestores the APP_DB entries as stale. This will be overwritten bynbrmgrdto trigger ARP but in case of Vlan, the member ports won't be added until later in the initialization, the packets won't get forwarded. This results in neigh entry to FAIL state and disrupts the warmboot requirements. Logs are captured below with timestamps of various eventsHow I verified it
