[jira] [Commented] (DRILL-7668) Allow Time Bucket Function to
Accept Floats and Timestamps

# [DRILL-7668](https://issues.apache.org/jira/browse/DRILL-7668): Allow Time Bucket Function to Accept Floats and Timestamps
## Description
Drill has a function `time_bucket()` which facilitates time series analysis. This PR extends this function to accept `FLOAT8` and `TIMESTAMPS` as input. Floats are typically not used for timestamps, however in the event that the data is coming from imperfect files, the numbers may be read as floats and hence require casting in queries. This PR makes this easier.
## Documentation
`time_bucket()` function now will accept a `timestamp` or `float8` as an argument for the time.
## Testing
Added two unit tests for the new data types.
