Subject: port Firestore Auth module in C++ (#733)

* Implement firestore/auth/user

* add user to project and some fixes

* implement firestore/auth/{credentials_provider,empty_credentials_provider}

* implement firestore/auth/firebase_credentials_provider

* refactoring firebase_credentials_provider and add (disabled but working) unit test

* add auth test to project

* address changes

* small fix to style and project

* fix the firebase_credentials_provider_test

* fix style

* address changes

* revert the change to static mutex_

* remove my custom plist path

* fix style

* address changes

* refactoring FirebaseCredentialsProvider to fix the issue w.r.t. auth global dispatch queue

* add /*force_refresh=*/ tag to bool literal for style purpose

* Use a shared_ptr/weak_ptr handoff on FirebaseCredentialsProvider (#778)

* Revert "refactoring FirebaseCredentialsProvider to fix the issue w.r.t. auth global dispatch queue"

This reverts commit 87175a4146267d403a774f138b85f8d3b532fa4b.

* Use a shared_ptr/weak_ptr handoff on FirebaseCredentialsProvider

This avoids any problems with callsbacks retaining pointers to objects
destroyed by a C++ destructor
