v.0.18.0

Improvements:

1. [LUNA-7962] Added support for working with custom features. It is now possible to obtain the expiration time for custom features.

• First, we try to get the expiration date. If the date is present, we return it.

• If there is no expiration date, we try to get the feature value. If the value is present, we return it.

• If there is no value, we check the availability of the feature. The value is set to None.

Bugs fixed:

1. [LUNA-7962] Fixed a caching defect affecting the results of different methods.
