[AIRFLOW-328][AIRFLOW-371] Remove redundant default configuration & fix unit test configuration

AIRFLOW-328
https://issues.apache.org/jira/browse/AIRFLOW-328
Previously, Airflow had both a default template for airflow.cfg AND a
dictionary of default values. Frequently, these get out of sync (an
option in one has a different value than in the other, or isn’t present
in the other). This commit removes the default dict and uses the
airflow.cfg template to provide defaults. The ConfigParser first reads
the template, loading all the options it contains, and then reads the
user’s actual airflow.cfg to overwrite the default values with any new
ones.

AIRFLOW-371
https://issues.apache.org/jira/browse/AIRFLOW-371
Calling test_mode() didn't actually change Airflow's configuration! This actually wasn't an issue in unit tests because the unit test run script was hardcoded to point at the unittest.cfg file, but it needed to be fixed.

[AIRFLOW-371] Make test_mode() functional

Previously, calling test_mode() didn’t actually
do anything.

This PR renames it to load_test_config() (to
avoid confusion, ht @r39132).

In addition, manually entering test_mode after
Airflow launches might be too late — some
options have already been loaded (DAGS_FOLDER,
etc.). This makes it so setting
tests/unit_test_mode OR the equivalent env var
(AIRFLOW__TESTS__UNIT_TEST_MODE) will load the
test config immediately, prior to loading the
rest of Airflow.

Closes #1677 from jlowin/Simplify-config

> Calling {{airflow.conf.test_mode()}} loads a new configuration object with the TEST_CONFIG, but it doesn't actually return it -- it appears that the TEST_CONFIG is never actually loaded. In other words, calling {{test_mode()}} doesn't actually do anything!
> This doesn't affect Airflow's unit testing process because the {{run_unit_tests.sh}} script explicitly points at the hardcoded {{unittest.cfg}} file.
