Update the documentation to reflect the changes on 0.8 release

[khorolets]

The 0.8 release will include some significant changes and will introduce a bunch of new things. We need to ensure all of the changes and new stuff is well documented and available to developers.

This includes:

• Lake Primitives documentation
• Update Lake Framework documentation

@khorolets Hello! Do we have a rough estimation for the 0.8 release roadmap? 🤗

Hi @raventid! I appreciate your interest in the 0.8 version. Unfortunately, I don't have the capacity to work on the new version at the moment. Honestly, I have not seen any community interest in this update.
If there are anticipators, I could prioritize it for the next month. Please share what you expect from 0.8 the most. It would help me to negotiate my capacity 😇

@khorolets Thank you for the reply! After playing around with the library I see that I'll have to use StreamerMessage anyway to convert blocks to our internal representation and almost all of the 0.8 features are not that useful to me :(
