Record opening and downloading resources

[dmcavoy]

Record firehose event when user clicks print pdf button on teacher lesson plan.

study: 'lesson-plan' or 'rollup-pages'
study_group: 'teacher-lesson-plan', 'student-lesson-plan', or 'resources-rollup'
event: 'download-resource' or 'open-resource'
data_json: includes resourceId
uuid included

Part of work for https://codedotorg.atlassian.net/browse/PLAT-339

like with #40071, it doesn't really work to mix onClick functionality with standard links, particularly when the onClick is making an HTTP request

Alright will make the same update here :)

LGTM after addressing comments.

if you've just got one thing in data json and you want it to be queryable, you could store it in data_int in addition / instead:

code-dot-org/apps/src/lib/util/firehose.js

Lines 12 to 23 in ed86d57

	* Usage:
	* firehoseClient.putRecord(
	* {
	* study: 'underwater basket weaving', // REQUIRED
	* study_group: 'control', // OPTIONAL
	* event: 'drowning', // REQUIRED
	* data_int: 2 // OPTIONAL
	* data_float: 0.31 // OPTIONAL
	* data_string: 'code.org rocks' // OPTIONAL
	* data_json: JSON.stringify(x) // OPTIONAL
	* }
	* );

my personal preference has been to store it in both places, so that the person writing the query can infer what the meaning of the data_int column is by seeing that it matches a named field in the data_json. since there is only one thing in data_json, this would let you proceed without further understanding of how this metric is going to be used.
