Update to Brave 6.0.1 (#587)

This commit updates to the latest Brave version (6.0.1). This revealed a
strange classloader issue for Zipkin2.Span when running the failover
sample app during the 'test' target. To get around this issue the
tracing dependencies are temporarily commented out in the failover
sample app.
