Allows customers to configure the sample_percent parameter. This API will NOT modify the sample_one_in_n rate. The sample_percent may be a decimal from [1, 100].
Old microsats are not capable of picking up the sample_percent change. For new microsats, 2022-04-28_17-39-22Z and later, the sample_percent takes precedence over any yaml-configured sample rate and sample_one_in_n set with the API. For all other microsats, the sample_percent ignored.
