Aurel/server hawk

[naure]

Goals of the PR is enabling smooth local development of the HNSW-based implementation of the SMPC protocol with all its infrastructure dependencies, as well as having a self-contained way of running the server without GPU dependencies.

Parts of the PR are:

• AWS stack through docker / LocalStack
• DBs using docker / postgres
• A self-contained server implementation that has no GPU dependencies

2 options to run locally:

1. Locally run a single server without Docker (recommended for quick iteration)

Step 1: run ancillary services

>>> docker-compose up localstack dev_db

Step 2: run service with the init script for Party 0

>>> ./scripts/run-server.sh 0 --init-servers # change to 1 or 2 for other parties

The script must run with --init-servers flag at least once. It will create some AWS resources, but after that it can run without it.

>>> ./scripts/run-server.sh 1
>>> ./scripts/run-server.sh 2 # in a separate shell

2. Run everything with docker

Just run

>>> docker-compose up

It will bring up the 3 parties plus all the needed AWS/DB resources

What else is missing

• SQS and SNS setup in LocalStack to send and receive messages, plus a lightweight client that can generate queries and send them to SNS/SQS
• Mapping of current inputs of iris-mpc-gpu to what iris-mpc-cpu expects. Namely, ensure that BatchQuery can be consumed by the HawkActor
• Mapping of the current outputs of iris-mpc-cpu to what we need to produce to be sent to SQS. In iris-mpc-gpu, this is encapsulated by the ServerJobResult. In iris-mpc-cpu, the construct used is HawkResult
