zebra: add several fields for debug

Browse Source 
Two changes for debug:
1. Add a field to indicate its vrf for nexthop.  When the interface changes
vrf, we can't easily know the vrf of this nexthop according to current log.
2. Add a field to indicate operation type.  We can't know whether to add or
remove route according to current log.

Before:
```
zebra_nhg_increment_ref: nhe 0x555623eb82c0 (76[if 6]) 0 => 1
zebra_interface_nhg_reinstall install nhe 75[77.75.1.75 if 6] nh type 3 flags 0x1
Route 77.75.1.0/24(8) queued for processing into sub-queue Early Route Processing
Route 77.75.1.0/24(8) queued for processing into sub-queue Early Route Processing
```

After:
```
zebra_nhg_increment_ref: nhe 0x555623eb82c0 (76[if 6 vrfid 9]) 0 => 1
zebra_interface_nhg_reinstall install nhe 75[77.75.1.75 if 6 vrfid 8] nh type 3 flags 0x1
Route 77.75.1.0/24(8) (add) queued for processing into sub-queue Early Route Processing
Route 77.75.1.0/24(8) (delete) queued for processing into sub-queue Early Route Processing
```
