Refactor get keyword value API exception handling

This commit refactors vpd specific utility API used to read value of a
keyword,in order to handle any exceptions thrown by it locally. All
utility methods should handle exceptions locally and log a journal log
in case of failure. The caller of the utility APIs should check the
return value to detect success/failure.

This commit also changes the caller of this API throughout the repo, in
order to check the return value.

Test:

```
- Install bitbaked image on Everest system
- After BMC boots, BMC should reach Ready state
- Check vpd-manager service status, should be active(running)
- Check no restarts in vpd-manager service
- Check vpd-manager "CollectionStatus" = "Completed"
- Check extra interfaces are processed properly
- Check backup restore working properly
```

Exception handling for json_utility APIs

This commit adds code to handle exceptions for some of the json_utility
APIs. Each API will have output returned in case of error based on the
return type of the API instead of throwing an exception.

Also updated the caller of the json_utility APIs to handle the return
value.
