Middleware contracts should publish an image containing smart contracts for integration testing

[shrimalmadhur]

Currently how we do integration testing is using foundry docker image and deploy all the contracts (eigenlayer contracts and middleware contracts) https://github.com/Layr-Labs/eigensdk-go/blob/67be9ea97fb92a3ee090ab12b56e34e97010a76d/cmd/egnaddrs/main_test.go#L50

But it would be great if middleware repo can publish a docker image of deployed contracts state which any repository (incredible squaring, eigenlayer-cli) can use as a base image to test onchain interaction

• [x] create design doc to make sure we're all on the same page
• [ ] get people to review the design doc
• [ ] published docker image with deployed eigenlayer core contract + eigenlayer middleware contracts.

+1 we really need this. This way also the contracts are published with consistent versioning, and a team can decide which versions of the contracts to test against, in a consistent manner (say if they decide to publish their contracts with older version of the middleware contracts)
