Current behaviour
When instantiating a Redis client using the current master branch of dd-trace-rb, and passing in a frozen options hash, an exception is raised:

FrozenError: can't modify frozen Hash: {:url=>"redis://localhost:6379", :timeout=>1.0}
    /home/runner/vendor/bundle-52/ruby/2.7.0/bundler/gems/dd-trace-rb-f387e1747a44/lib/datadog/tracing/contrib/redis/patcher.rb:24:in `initialize'

Expected behaviour
It should not raise an exception :) This was broken a few days ago in #2363 I believe

Steps to reproduce

Redis.new({}.freeze) should do it I think?

How does ddtrace help you?

It rocks! Really looking forward to rolling out the new native profiler implementation.
