azure-identity related tests are failing due to the lettuce-core and redisson dependencies resolving Netty versions to a lower version than required by Reactor Netty. @billwert, @g2vinay could you look into these dependencies

[saragluna]

@alzimmermsft, do you think this is an option? Azure Core Http Netty only depends on parts of netty's libs, which could lead to unmatched netty versions when working with other libs also depending on netty:

That looks good to me to resolve this issue in the short term. I've been talking with @billwert and @g2vinay on what we want to do long term about these test dependencies.
