Click handlers were not getting attached to DOM elements in some cases on slow running machines.
Added logic to attach handlers when elements are ready.
Added 2 buttons on metrics tab:
Download Subsection Data for downloading to csv.
Download Problem Data for downloading to csv.
This commit updates lms/templates.
These keys are now objects with a limited interface, and the particular
internal representation is managed by the data storage layer (the
modulestore).
For the LMS, there should be no outward-facing changes to the system.
The keys are, for now, a change to internal representation only. For
Studio, the new serialized form of the keys is used in urls, to allow
for further migration in the future.

[LMS-2370]
Clicking on any of the bars displays a list of students for that
particular action (either opened the subsection or attempted the
problem).
Students are listed for the sub-sections.
Students, grade and percent are listed for the problems.
The on-screen list displays only the first 250 students with
an overflow message if there are more students than that.
The csv download lists all students.
Metrics tab shows student data:
-Count of students opened a subsection
-Grade distribution per problem
for each section/subsection of the course.
Implemented for both the old and beta dashboard
Controlled by a feature flag 'CLASS_DASHBOARD'
Data is aggregated across all students
Aggregate data computed from courseware_studentmodule
