dev: batch RPC requests linked to storage queries

[greged93]

Describe the enhancement request The json RPC standard allows to send a batch of request (see link and link). This would allow us to batch the requests to the node for storage requests in the context of a call for example.

Describe Preferred Solution

• Verify batch request is available on Juno.
• Verify it is possible to build and send a batch request in Rust.
• Explore the different hotpoints on our code where batching would improve the latency.
• Implement a wrapper type in order to perform batch requests to a starknet json rpc.
• Batch calls where possible

hey @hhamud this is quite a complicated issue so probably better not if you don't have a lot of experience with our stack. This is actually still blocked for now anyway, waiting for this https://github.com/xJonathanLEI/starknet-rs/pull/600 PR on starknet-rs.
