Functional test for hourly microbatch model

[dbeatty10]

Resolves #11165

Problem

For hourly microbatch models that run concurrently (like Snowflake), the batch id can have spaces which causes an invalid name for the temporary table and leads to a database error.

Solution

Only use alphanumeric characters within batch ids.

Since the most granular batch size is hour, the simplest solution might be to use the ISO8601 basic format for time using an hour granularity:

    def format_batch_start(batch_start: datetime, batch_size: BatchSize) -> str:
        return batch_start.strftime("%Y%m%dT%H")
