[MCKIN-9474] [BB-873] Support for filters, and multiple roots in problem response reports

[xitij2000]

This PR adds two features to the problem response report API:

1. Support for specifying multiple root blocks.
   With this feature, you can now pass a comma-separated list of problem locations, and the generated report will include both of them (and children).

2. Support for specifying a problem type filter.
   This feature allows you to request a report for only one or more types of problems.

• I tested this:

1. I used the EdX Demo Course as base for testing this.
2. Generate problem response reports for 2 problems sending comma-separated values.
3. Checked that the report was correctly generated and responses for both problems were included ✔️
4. Used section block-v1:edX+DemoX+Demo_Course+type@chapter+block@graded_interactions and tested the problem_types_filter with three values:

• openassessment
• problem
• openassessment,problem

5. Checked that the generated reports contained only the problems that were specified on each operation ✔️
6. Checked that we can generate a problem response report for the entire course with block-v1:edX+DemoX+Demo_Course+type@course+block@course

• I read through the code
• Includes documentation: on the docstrings
• I checked for accessibility issues NA

Nice work! This is ready to merge. 😁

To make testing this easier, I logged in LMS on Chrome, generated a problem response report and copied a cURL request that looked like this:

curl 'http://lms.mcka.local/api/instructor/v1/course/course-v1:edX+DemoX+Demo_Course/reports/problem_responses' -H 'Pragma: no-cache' -H 'Origin: http://lms.mcka.local' -H 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: en-US,en;q=0.9' -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.96 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' -H 'Accept: application/json, text/javascript, */*; q=0.01' -H 'Cache-Control: no-cache' -H 'X-Requested-With: XMLHttpRequest' -H 'Cookie: openedx-language-preference=en; djdt=hide; csrftoken=nYvaNAd0020JjeC5B86H26T2mS2dKnMQ; sessionid=7czmuk4ij6r5c0ka3xitl5dbeql8mvmf' -H 'Connection: keep-alive' -H 'X-CSRFToken: nYvaNAd0020JjeC5B86H26T2mS2dKnMQ' -H 'Referer: http://lms.mcka.local/courses/course-v1:edX+DemoX+Demo_Course/instructor' --data 'problem_location=block-v1%3AedX%2BDemoX%2BDemo_Course%2Btype%40chapter%2Bblock%40graded_interactions' --compressed
