Add the missing fields needed on course_metadata so we can accept all data from publisher LEARNER-2459

email content. It is not intended for public consumption of any form.

Adding person in discovery throws 500 if family name is
empty. Person expects family name to generate full name.
This fix would enable family name to be empty as its not a
required field.

It is unclear what purpose these query counts serve. So far they have only served to slow down my own development on new functionality. If we actually need to optimize query counts in the future, we can do so where necessary.

We want to avoid using the setup method when possible as it is broken
and makes three useless API calls.

This reverts commit a6c66e55.

The previous attempt to resolve this issue did not work. Now we are
explicitly removing the code that made unnecessary Elasticsearch calls.

LEARNER-2229

Haystack attempts to always ensure the index mapping is up-to-date.
There is a bug in this code (at least when using Elasticsearch 1.x) that
results in an invalid mapping comparison. Given that our mapping is
static, this feature is simply a waste of resources since we always
make three API calls to Elasticsearch for every search call.

This commit disables this mapping check/update feature when executing a
search query.
