Elastic Scaling

[filippoweb3]

Add information about elastic scaling: how parachains will be able to reserve time on multiple cores and thus include multiple parablocks in a relay chain block at the same time, while producing parablocks < 6s

Some info:

• Elastic Scaling paritytech/polkadot-sdk#1829
• https://polkadot.network/blog/elevating-polkadots-performance-and-scale-with-asynchronous-backing

@CrackTheCode016, asking for a preliminary review of the concept and broad mechanics ;)

[CrackTheCode016]

Left a few comments and suggestions, overall looking good. Some thoughts:

• Since this isn't implemented yet, I would suggest we move this to Future Implementations

• I am not sure we should have the challenges section, although I am open to keeping it if it facilitates understanding of the topic.

@CrackTheCode016 I addressed your feedback. Let me know if it is ok with you ;)

[CrackTheCode016]

I would need to read more on core regions and how those will play a part, as I understand, that is the basis for how elastic scaling will take place (see here),

I think that detail should be added before it is merged. I'd like to dive a little deeper also into the technical implementations, and really ensure this is accurate before approving.

As a sidenote, having a dedicated page for coretime will accompany this page would be beneficial, as the two concepts go hand-in-hand. It would even be good to include a section on how the two relate, to clear up any confusion!

@DrW3RK @CrackTheCode016 let me know if this PR is good to go. On a high level is informative and I think it covers what elastic scaling will bring to Polkadot. In a second PR I could make better figures.

[CrackTheCode016]

Although I myself am not terrible familiar with the specifics of elastic scaling, it appears sensible to me and we can update it in the future.

[CrackTheCode016]

Of course, if elastic scaling improves time in this manner, than naturally they would also have to pay more for this throughput ;)

[DrW3RK]

Added more context on Elastic scaling and provided info on the phased rollout of its implementation.

The last section with figures and times will benefit from a review from the elastic scaling implementors.

@DrW3RK who would you suggest to give a final review on this PR?

[DrW3RK]

@eskimor We are working on adding a high level Wiki doc on Elastic scaling. When you get time, could you please go over the content on this PR and provide feedback? Thank you.

Looks good.
