Commit transaction so for next test run we are sure that data_stream has no data and it doesn't affect test execution.

created thus it is needed to wait for server side activities to be
processed

For backward compatibility with ingestion policy scripts, the message body is
turned into a 'data_chunk' request parameter.

By not having anymore to convert to/from application/x-www-form-urlencoded,
this fixes a severe performance issue, in particular when ingesting a lot of
data with fluentd (Ruby uses regex to convert).

Data ingestion batch does not have validation workflow, so
we cannot validate it.

Ingestion operations which write to data stream do not
have bucket_reference parameter. Now we do only pass
this parameter if we get it from the tag parsing script.

Transformation at append of data to Data Stream is triggered by an activity not at append time any more thus test is redundant.
