Add gst_vaapi_encoder_set_keyframe_period() interface to allow the user control the maximum distance between two keyframes. This new property can only be set prior to gst_vaapi_encoder_set_codec_state(). A value of zero for "keyframe-period" gets it re-evaluated to the actual framerate during encoder reconfiguration.
