For Tag v2.0, implement reading from the specified path location

[MasterHardik]

• Instead of taking the file as input via java.nio.buffer, modify the code to read it directly from a specified path location.
• For that, in tag v2.0, pull a branch first.
• Make the changes in the .ftl file by providing a text input for the file path.
• Update the service to include mode="IN" and add another attribute named filePath.

• Changes are to be done on branch enhancement/scale-DOM-parser.
• Followed by the below mentioned issue.
