The auth methods returns a specific error code “ErrInvalidCredentials” in cases where it fails due to invalid credentials for existent users.
This helps to differentiate between existent and not existent users when lockout feature is implemented to prevent brute forcing
This is only used for handling lockouts and will be removed before return. This will not be returned or seen externally.
These changes are for approle, ldap and userpass auth methods
Added changes to RespondErrorCommon and also added a test to confirm that ErrInvalidCredentials is not seen externally.

Are the ErrInvalidCredentials changes only for the Approle and Userpass login endpoints?
