Default contract limits should be the same as on Starknet

[FabijanC]

Description

True, users can configure the limits related to request size and similar (as documented here), but ideally their default values would be equal to the ones used by Starknet. This was reported to me on Telegram in a private message.

To limit the contract size (not the request size), this method from blockfier can be used: ContractClass::bytecode_length and the constants specified here, as mentioned on Slack

Classification

If already being able to configure the limits is satisfying, then this issue is merely an enhancement proposal. One might argue that this is a bug, so I'm also putting both labels.

Questions

How should it be implemented? Should there be something which automatically fetches the limits from a trusted source? Should the values be updated manually, but regularly?
