Dynamic Trace Sample Rate

[codeforaliving]

Hello,

We currently have a custom extension with a SpanProcessor. For traces, we are using the following config:

otel.traces.sampler.arg=1.0

Is there a way to reload the sampler arg at runtime? We went down the path of implementing a custom TraceIdRatioBasedSampler but we are not sure how to get the updated sample rate from our Spring Boot app into a dependency and ultimately to the extension JAR. We are using version 1.14.0. Thanks in advance.
