Description

From Sampler spec

GetDescription

Returns the sampler name or short description with the configuration. This may be displayed on debug pages or in the logs. Example: "TraceIdRatioBased{0.000100}".
Description MUST NOT change over time and caller can cache the returned value.

This implies rate should not be changed after instantiation, hence removing the rate setter from TraceIdRatioBasedSampler. Adding cache doesn't really change anything as there are no computationally expensive operations.

LGTM. Might be worth raising an issue to the spec to clarify that you can't change the sampler after instantiation.

Yes, that would make it clear for others also. I will create an issue.
