vpd-tool force reset command implementation

This commit implements force reset command option in vpd-tool
application.

The commit implements clearing of Phosphor Inventory Manager’s (PIM)
persisted data, restarts the PIM and VPD manager services. In turn VPD
manager triggers the VPD collection for the FRUs listed in the system
config JSON.

Output:
```
