We never ran the cleanup method for the OTLP fake server, which means we never shut it down properly. This would leak threadpool executor threads. We also need to reset the tracing configuration at the end of tests, otherwise subsequent tests will end up using the tracing provider from the previous test. This is because we currently only run the reset at the start of a test that using tracing; so new tests that startup without using tracing won't run the provider reset. This change corrects both issues, which should mean that the tracing configuration is isolated to the currently running test. Change-Id: Ib1edf51ad8ef3550b16dc888883f86a96bfb2dc2
