Allow an optional HTTP header, `X-AthensDB-Partition-Key-Salt` to be set in HTTP requests sending data to the cluster that adds a salt to the partition key which can be used to better distribute data across the cluster. One use for the partition key salt is to support multiple tenants; by using the tenant ID as the salt, data will be more evenly distributed if multiple tenants try to write the same time-series.
HTTP is an acronym, make it all caps.
