The validation of the exponential histogram, already performed in sdk/metric/aggregation, is duplicated in the exponential histogram implementation (sdk/metric/internal/aggregate). The view will use the Err from ExponentialHistogram in sdk/metric/aggregation to validate the configuration prior to getting here:

Having a duplicate validation of the configuration here will lead to two parts of the code-base doing the same thing and introduce the possibility for many bugs.

Similar to the explicit bucket histogram, we should just assume the configuration passed here is valid and proceed.
