vpd-tool force reset command

This commit implements ‘force reset’ user option in vpd-tool. Command
clears the BMC persisted data and recollects the VPD for all the FRUs
mentioned in system config JSON.

Command will only be processed if chassis is powered off.

stub API is added in VpdTool class to implement this command.

Output:
```
root@p10bmc:/tmp# obmcutil state
CurrentBMCState : xyz.openbmc_project.State.BMC.BMCState.Ready
CurrentPowerState : xyz.openbmc_project.State.Chassis.PowerState.On
CurrentHostState : xyz.openbmc_project.State.Host.HostState.Running
BootProgress : xyz.openbmc_project.State.Boot.Progress.ProgressStages.MemoryInit
OperatingSystemState: xyz.openbmc_project.State.OperatingSystem.Status.OSStatus.Inactive

When chassis is powered on, force reset command will fail:
root@p10bmc:/tmp# ./vpd-tool -f
The chassis power state is not Off. Force reset operation is not allowed.

vpd-tool mfgClean: Sync BIOS attributes stub

This commit adds --syncBiosAttributes flag to vpd-tool --mfgClean
option. The changes in this commit allows user to specify
--syncBiosAttributes/-s with --mfgClean option. --syncBiosAttributes
flag when used along with --mfgClean will sync those VPD keywords on
hardware and D-Bus, with the corresponding values of BIOS attributes.
The other keywords not associated with BIOS attribute backup continue to
be updated with the default value in backup_restore JSON file.

Test:

```
root@p10bmc:~# vpd-tool
VPD Command Line Tool
Usage: vpd-tool [OPTIONS]

Options:

-s,--syncBiosAttributes Sync BIOS attribute related keywords from
BIOS Config Manager

MfgClean:
Flag to clean and reset specific keywords on system VPD to its default
value.
vpd-tool --mfgClean
To sync BIOS attribute related keywords with BIOS Config Manager:
vpd-tool --mfgClean --syncBiosAttributes
```
