     * until one returns an AuthToken.
     *
     * If any provider in the chain throws AuthTokenException,
     * it will be stored and re-thrown to caller at the end.
     *
     * If more than one provider throws AuthTokenException then exception reported
     * by last provider will be thrown to caller.
     *
     * If AuthProviderException is thrown by provider then-
     *    - For AuthProviderException that is ignorable(AuthProviderException.NO_AUTH_TOKEN, AuthProviderException.NOT_SUPPORTED),
     *      it will be logged and next provider will be tried.
     *    - For AuthProviderExceptions that is not ignorable, AuthTokenException is generated and stored,
     *      thrown at the end if all provider fails.
     *
     * Return null when all providers fails to get AuthToken and no exception thrown by any provider.
