* Add enablePrometheus annotation.
The PR adds the enablePrometheus annotation to load tests that are
part of PSM data plan performance tests. This annotation enables
all PSM related tests to obtain data from Prometehus, even for the
regular tests.
* Add templates for PSM test.
The commit adds psm related template generated from
loadtest_template.py. This commit also update the
loadtest_example.sh to generate examples based on the templates.
* GKE benchmarks: add support for benchmarking grpc-dotnet
* add dotnet to loadtest basic templates
* print full path for generated examples
* add grpc-dotnet scenario to loadtest_example.sh generator
* add grpc-dotnet to the experimental kokoro job
* yapf format code
* Update load test template and config generation.
This change includes the following features and fixes:
* Add a script to generate load test examples.
* Update template generation logic to support round trip from configs to templates (handling of repeated clients and servers for the same language and of named clients and servers in source configs).
* Integrate safe language names from scenario config.
* Update template and config formatting (now that we generate in round trip).
* Fix shellcheck lint warnings.
* Update README.md.
