[SL-1617] [Feature] Enable time constraints with agg_time_dimension instead of metric_time

[courtneyholcomb]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing metricflow functionality, rather than a Big Idea better suited to a discussion

Describe the feature

Currently, time constraints only work when queried with metric_time. Since metric_time represents agg_time_dimension, you should be able to replace metric_time with the agg_time_dimension and get the same behavior.

@jordan.stein this isn't in progress yet!

@jordan.stein also - why high priority? time constraint params are only supported in the MF CLI, not any of our APIs, so this seems like a lower prio!
