METRON-1584 Indexing Topology Crashes with Invalid Message
If the indexing topology receives a message containing invalid JSON, the
topology will crash. The topology needs to handle these types of errors and
continue processing.
## Changes
* Updated the `BulkWriterComponent` to allow tuples that do not contain
valid JSON messages to be error'd out.
* Updated `BulkMessageWriterBolt` to handle the case where a tuple does not
contain a valid JSON message.
* Updated the BulkMessageWriterBolt unit tests to validate that error'd
messages are being ack'd and emitted on the correct error stream. Previously a
mock was being used that hid a bug with the `BulkWriterComponent`.
* Added a unit test for the case where an invalid message is sent as input
to the indexing topology.
## Testing
1. Spin-up the development environment.
1. Ensure that messages are successfully being indexing by running the
Service Check and/or validating the Alerts UI.
1. Write an invalid message to the "indexing" topic.
1. Ensure the invalid message is sent to the "error" topic.
1. Ensure the indexing topology did not crash.
