Support for `Provider_name` and `Data[x]` notation to the field mapping

[fukusuket]

Currently, the field mapping feature does not support following point:

• Provider_name matching
  • e.g. Since the Application log has multiple Provider_names, we need to convert the field value only when the Provider_name matches.(in addition to Channel, EventID)
• Data[x] notation filed mapping

We want to support following rule/field conversion, so I'll implement above point.
