* Default to new backend endpoint if the endpoint in current context does not match existing set in constants.

* Remove some env references.

* Added comments with reasoning for selecting new backend by default.

* Update comment.

* Remove all references to useNewPortalBackendEndpoint now that old backend is disabled in all environments.

* Resolve lint issues.

* Removed references to old backend from Cassandra and Mongo Apis

* fix unit tests
