Deduce StreamName from StreamARN for Kinesis when StreamName not provided

[robcarlan-datadog]

Summary of changes

DSM does not submit data when requests are sent with StreamARN rather than StreamName. The cilent allows providing either, but recommends sending the full StreamARN instead (docs). So if people follow the AWS docs, they will not see DSM data.

We fix this by using a deduced StreamName from the StreamARN if provided to supply the streamname tag.

This is pretty much the same logic as we use in the Java tracer: here.

Reason for change

People using .NET & Kinesis won't see DSM data if they use use the StreamARN parameter, leading to a bad user experience.

Implementation details

This only affects the PutRecord/PutRecords (sync & async) requests. GetRecords always uses the stream ARN, and we use the same logic of deducing a stream name from the StreamARN to create the context on the receiving side. AWS Docs

We have to split the Kinesis instrumentation into two, as the new field is only introduced in v3.7 and above.

Test coverage

Added unit tests for the name deduction logic, existing integration tests cover versions below 3.7 and above, so test both instrumentations. The test doesn't use the StreamARN parameter, which I tested manually.

Execution-Time Benchmarks Report :stopwatch:

Execution-time results for samples comparing the following branches/commits:

• This PR (7134)
• master

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

• Welch test with statistical test for significance of 5%
• Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
