Hotfix: fix export data

[bcb37]

This pr:

• removes the queries to 'monitored_decision_point' and 'monitored_decision_point_log' and replaces multiple rows with different MarkExperimentPointTime values with a single row with MarkExperimentPointTime coming from the enrollment table
• avoids including metrics columns that do not correspond to queries defined in the experiment
• fixes the display of metric keys

@bcb37 So wanted to confirm one thing, you are now showing the attribute metric (timeSeconds) instead of the class (masteryWorkspace) for a grouped metric in the metrics column, right? Should we show the complete grouped metric (Class -> Key -> Attribute)? I have attached screenshot for other to see the difference. The old export gives 2 rows for each of the 2 students and the new one as per this PR gives 1 row for each of the 2 students. This is working perfectly as expected.

Also, didn't get the 2nd point of this PR description. Which metric column will not be shown? We already show the metrics that are used in the experiment. Can you please elaborate this scenario a bit. Thanks

@ppratikcr7 it was including metrics columns from other experiments because the metrics list wasn't restricted to just the metrics in the current experiment. So I fixed that.
The screenshot is from a prod export of an experiment that does not have queries "Percent Graduated", "Swap", etc.
