v.0.22.0

Improvements:

1. [LUNA-7732] Image modification estimator added for resources /estimator and /sdk. Threshold is adjustable via service settings upon LUNA_REMOTE_SDK_IMAGE_MODIFICATION_ESTIMATOR_SETTINGS.estimator_settings.threshold The default value is set to 0.5, which means that any upper score will be considered as an unmodified image. Estimator is disabled by default.

2. [LUNA-7734] An image queue size for estimations was limited. Default size is equal to 200 now. Previously, the application could use a lot of RAM when request processing lagged, leading to unmanaged RAM accumulation and potential performance issues

Bugs fixed:

1. [LUNA-7734] Image processing hang has been fixed in some cases.
