The previous version of this code used the Django Setting
ENABLE_WAFFLE_FLAG_METRIC to determine whether to add a single
metric with a dict of details about all flags. Due to
NewRelic's 256 character limit on the metric value, this was
getting truncated.
This new version instead uses the Django Setting
WAFFLE_FLAG_CUSTOM_METRICS, a list of waffle flag names to
instrument.
The name of each custom metric will match the name of the flag.
The value of the custom metric could be False, True, or Both.
The value Both would mean that the flag had both a True and False
value at different times during the transaction. This is most
likely due to having a check_before_waffle_callback, as is the
case with CourseWaffleFlag.

- Have it load dates from edx-when, not just write to it. This
fixes self-paced courses where edx-when is only place dates are
kept.
- Have it read original date for a homework from edx-when when
resetting a date. This fixes the message it gives the instructor
about whether it was successfully reset.
- Have it recursively set a date, rather than assuming that dates
are only ever set on the subsection layer. This fixes setting
dates on self-paced courses (where dates are set all the way
down) and just in case somebody somewhere edits the course xml
to have a date where it's not expected.
Updating edx-when version to pull in a change related to not
returning dates if the enrollment happened after course end
(if no enrollment end date is set)
Fixing 56 GuessedAtParserWarnings, in commit edx#24098
Background: BeautifulSoup automatically picks the fastest parser available. By default, it picks the "lxml" parser.
Per the [BeautifulSoup](https://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-a-parser) documentation:
> Beautiful Soup supports the HTML parser included in Python’s standard library, but it also supports a number of third-party Python parsers. One is the lxml parser. Depending on your setup, you might install lxml with one of these commands.
> Another alternative is the pure-Python html5lib parser, which parses HTML the way a web browser does.
Context: We changed two statements, one in lms and another in openedx. Both statements fire up BeautifulSoup. Now we explicitly ask for "lxml," following the recommendation on BeautifulSoup's documentation:
> If you can, I recommend you install and use lxml for speed. If you’re using a very old version of Python – earlier than 2.7.3 or 3.2.2 – it’s essential that you install lxml or html5lib. Python’s built-in HTML parser is just not very good in those old versions.
Before:
`soup = BeautifulSoup(content)`
After:
`soup = BeautifulSoup(markup=content, features="lxml")`
The warnings are gone, tests are passing in local.
* Hide private team-sets from users not on a team
* Modify add team count to factor in team visibility
* Fix bug that broke search w/in private team-sets
If setting ENABLE_WAFFLE_FLAG_METRIC is True, a custom
metric will be added with the values of all WaffleFlag
and CourseWaffleFlags seen during the transaction.
Metric flag values could be False, True, or Both.
The value Both would mean that the flag had both
a True and False value at different times through
the transaction. This is most likely due to having a
check_before_waffle_callback, as is the case with
CourseWaffleFlag.
Example metric value:
"{'another.course.flag': 'False', 'some.flag': 'False', 'some.course.flag': 'Both'}"
Warning: NewRelic does not recommend large custom
metric values due to the potential performance
impact on the agent, so you may just want to
enable when researching usage of a particular flag.
Metric values longer than 255 are truncated.
TODO: A how_to can be added later if we find this
useful, including helpful querying tips.
