Add `groupby` options for datetime values in the UI

If you have a date or a time column, then we should automatically make this into a toggle-list in the UI.

E.g. if I had created_at_timestamp in dbt, it would appear like this in Lightdash:

• created_at_timestamp

  created_at_time created_at_date created_at_week … etc.

Alternative, sleeker option:

• created_at_timestamp

  time date week … etc.

But, when you select one of the options, it puts it on the results table as created at week (for example)

Super awesome!

I almost feel like order date shouldn’t be click-able (as in, this shouldn’t be true: “We can always select the main/original dimension”)

@ZeRego @owlas summary of our chat:

• we want to go with option 1: time intervals are split out into separate dimensions.
• The way you define time intervals is using a parameter called time_intervals. You can set this to default or set the time interval values you’d like. Default intervals are: [time, day, week, month, year] --> if the dimension is a date then we remove the time default value.

Interval options are: time, millisecond, second, minute, hour, day, week, month, year

name: date
  meta:
    dimension:
      time_intervals: default

OR

name: date
  meta:
    dimension:
      time_intervals: [year, month, day]

• If you have selected a dimension to have time intervals, then we’ll group all of the related dimensions within the original dimension name
