Building and running tests as a developer

CI tests can be run on docker by invoking the script ./ci/run_docker.sh ./ci/do_ci.sh {TARGET} where the targets are:

cmake.test: build cmake targets and run tests.
cmake.legacy.test: build cmake targets with gcc 4.8 and run tests.
cmake.c++20.test: build cmake targets with the C++20 standard and run tests.
cmake.test_example_plugin: build and test an example OpenTelemetry plugin.
cmake.exporter.otprotocol.test: build and test the otprotocol exporter
bazel.test: build bazel targets and run tests.
bazel.legacy.test: build bazel targets and run tests for the targets meant to work with older compilers.
bazel.noexcept: build bazel targets and run tests with exceptions disabled.
bazel.nortti: build bazel targets and run tests with runtime type identification disabled.
bazel.asan: build bazel targets and run tests with AddressSanitizer.
bazel.tsan: build bazel targets and run tests with ThreadSanitizer.
bazel.valgrind: build bazel targets and run tests under the valgrind memory checker.
benchmark: run all benchmarks.
format: use tools/format.sh to enforce text formatting.
third_party.tags: store third_party release tags.
code.coverage: build cmake targets with CXX option --coverage and run tests.

Additionally, ./ci/run_docker.sh can be invoked with no arguments to get a docker shell where tests can be run manually.
