Finatra 20.1.0

Changed

• finatra: Exposing Listening Server's bound address in Thrift and HTTP server traits
  c17f55df
• finatra: Upgrade logback to 1.2.3 445ddf89

Fixed

• inject-server: Fix issue in c.t.inject.server.EmbeddedHttpClient where assertion of an
  empty response body was incorrectly disallowed. This prevented asserting that a server
  was not yet healthy as the /health endpoint returns an empty string, thus even a not yet
  healthy server would report as "healthy" to the testing infrastructure as long as the health
  endpoint returned a 200 - OK response. e9aa2dac
