Add new tag `_dd.integration` to be used for a metric on integration usage

[vandonr]

Summary of changes

Add a new tag to spans at serialization time, that copies the value of the component tag, EXCEPT if it was set before, which should be done for all code paths that are not DD instrumentations. The goal is to capture the instrumentation name, or "otel" or "opentracing". This data is then read in our ingestion pipeline to send a metric representing the number of spans ingested for a particular instrumentation.

Reason for change

https://docs.google.com/document/d/1N5EpaBy7aywnFoBVXs5E7M2-6oeQWOBKDNf67Yvxhpo is the original RFC. Overall, the benefit of this over the span_created data is that:

• since it's sent from the backend, we can categorize it, and make changes to that categorization
• it measures the spans that actually reach datadog
• it doesn't require adding a manual line of code every time a new instrumentation is created (there is something to do if we add new ways to create manual spans, but that's a lot rarer)

Implementation details

Since I'm going to access the component tag, and I noticed pretty much all integrations need to set it, I pulled it up from the individual Tag classes to the parent one (InstrumentationTags) to be able to query it efficiently. Some instrumentations set it to a constant, others set it dynamically, so I went for a get; set;, which is removing the "readonlyness" from some Tag classes, but I think it's not a big deal.

Test coverage

added tests on Spans and edited the serialization test to make sure the custom tag is written.

Execution-Time Benchmarks Report :stopwatch:

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

• This PR (7093)
• 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).
