feat: set paramter bucket_max_span_seconds in timeseries collection creation

[retoflow-fricke]

• set bucket size for timeseries collection creation
• consider using bucket_max_span_seconds if you expect to query data for fixed time intervals, such as every 15 minutes starting at midnight. Ensuring buckets don't overlap between those periods optimizes for high query volume and insert operations
• this option increases the performance if the correct bucket size is set, at least 5 fold

Granularity is currently hard-coded to "minutes".
In mongodb granularity is an optional parameter defaulting to seconds.

To be in line with the upstream API, shouldn't we also add granularity as an optional argument (not setting it if None -> defaults to seconds), and throw an error if both granularity and bucket_max_span_seconds are passed?
