* Renamed OAuth2Authentication to BearerAuthentication
* Added back OAuth2Authentication name
-there are libraries such as edx-enterprise that still import OAuth2Authentication. The OAuth2Authentication class should be fully removed when everything is importing BearerAuthentication correctly
- Removing deprecated auth classes
- Replacing OAuth2AuthenticationAllowInactiveUserDeprecated with OAuth2AuthenticationAllowInactiveUser
- the old class was a child class of a deprecated class that we are removing and replacing.
Currently, we are working on removing the rest_framework_auth library from edx-platform. For this push, we need to remove the oauth2Authentication class. This PR creates a new class oauth2AuthenticationDeprecated that adds additional new relic metrics. The metrics would allow us to see how often this class is used and its success rate. The hope is that this information will help us with transitioning to a different authentication class.
The update (PUT) endpoint now supports creating new CreditCourse objects in addition to updating existing ones. This functionality greatly simplifies the logic needed by consumers (e.g. the Course Administration Tool) to create or update CreditCourse objects.

Floating point values should be treated as strings to ensure values such as 1.0 are not converted to 1. Such conversion invalidates the signature generated for the credit request. Additionally, JSON has no concept of a floating point datatype.
ECOM-2172
CSRF protection needs to be disabled so that requests made using OAuth and other non-session-based authentication mechanisms can be properly processed. If session authentication is used, DRF will enforce CSRF protection.
XCOM-524
Endpoints support create, read, and list operations.
NOTE: This commit also includes a retrofitted SimpleRouter that supports overriding the lookup regex. This retrofit is simpler to implement than updating edx-ora2 which is pinned to DRF 2.3.x.
XCOM-524
* Add end-point for initiating a request for credit from a provider.
* Add an end-point for a provider to update the status of a request (approved / denied).
