/**
* This method creates an ALTS zero-copy grpc protector.
*
* - key: a symmetric key used to seal/unseal frames.
* - key_size: the size of symmetric key.
* - is_rekey: use rekeying AEAD crypter.
* - is_client: a flag indicating if the protector will be used at client or
* server side.
* - is_integrity_only: a flag indicating if the protector instance will be
* used for integrity-only or privacy-integrity mode.
* - max_protected_frame_size: an in/out parameter indicating max frame size
* to be used by the protector. If it is nullptr, the default frame size will
* be used. Otherwise, the provided frame size will be adjusted (if not
* falling into a valid frame range) and used.
* - protector: a pointer to the zero-copy protector returned from the method.
*
* This method returns TSI_OK on success or a specific error code otherwise.
