import command doesn't throw error for invalid json #175

Currently, abc doesn't throw an error when we have an invalid JSON file, rather it succeeds with 0 records inserted.

How to replicate

• Create an invalid JSON file. Here file has extra ,

echo '[
  {
    "name": "jame",
    "email": "jame@yopmail.com",
  }
]' > test1.json

• Try abc command
  abc import --src_type=json --src_uri=test1.json --log.level=debug http://admin:admin@localhost:9200/test

• abc version used here: 1.0.0 Preview Release 2

Expected output

Command should throw an error with correct exit status, if the command fails
