Edx-django-utils

--------------------

Updated
~~~~~~~

* Exposing all public functions in edx_django_utils/plugins directory in its __init__.py file.
* this was done to keep inline with standard/pattern used in other packages in edx_django_utils

--------------------

Added
~~~~~

* Adding Plugin infrastructure
* Allows IDAs to use plugins

--------------------

Added
~~~~~

* Improved documentation for CodeOwnerMetricMiddleware, including a how_tos/add_code_owner_custom_metric_to_an_ida.rst for adding it to a new IDA.
* Added ignore_transaction monitoring utility to ignore transactions we don't want tracked.

Updated
~~~~~~~

* Moved transaction-related monitoring code into it's own file. Still exposed through `__init__.py` so it's a non-breaking change.

--------------------

Updated
~~~~~~~

* Added a catch-all capability to CodeOwnerMetricMiddleware when CODE_OWNER_MAPPINGS includes a '*' as a team's module. The catch-all is used only if there is no other match.

--------------------

Added
~~~~~

* Added get_current_transaction for monitoring that returns a transaction object with a name property.

Updated
~~~~~~~

* Updated CodeOwnerMetricMiddleware to use NewRelic's current transaction for cases where resolve() doesn't work to determine the code_owner, like for Middleware.

--------------------

Added
~~~~~

* CodeOwnerMetricMiddleware was moved here (from edx-platform) in order to be able to take advantage of the ``code_owner`` metric in other IDAs. For details on this decision, see the `ADR for monitoring code owner`_. See the docstring for more details on usage.
