Allow histograms to record measurements with negative values

2

**Describe the bug** Looking at [SdkDoubleHistogram.java](https://github.com/open-telemetry/opentelemetry-java/blob/8fd45a771c85584c9f710767dfe82bc458421358/sdk/metrics/src/main/java/io/opentelemetry/sdk/metrics/SdkDoubleHistogram.java#L46) we block negative values in histograms despite this being supported under exponential histograms (via negativebuckets). Is this intentional or just a side effect of...

Update spec to permit negative observations of native/exponential histograms?

6

**What are you trying to achieve?** The current [spec language](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#histogram-operations) prevents observations of negative values of Histograms: > The value is expected to be non-negative. This API SHOULD be documented...
