feat(prefect executor): v1 for sandbox use

[lmeyerov]

Adds initial docker-compose for operating a prefect executor

Use from ProjectDomino parent folder:

echo "PREFECT__SERVER__HOST=PREFECT.SERVER.IP.HERE" > .env

sudo docker-compose -f ./ProjectDomino/infra/pipelines/docker/docker-compose.yml up -d prefect-agent

sudo docker ps

Next:
-- Change Dockerfile to be a layer off graphistry-blazing + whatever else we add
-- Healthcheck + prometheus hook

WIP, will only merge after we get it working :)

Just discovered we should also set PREFECT__SERVER__UI__HOST and PREFECT__SERVER__UI__PORT - don't think it matters that much but without them the logged URLs will be incorrect (localhost instead of the actual host). @lmeyerov could you add them in this PR or I can add them later?

[ZiyaoWei]

I guess I can also commit to this branch :-) Might do that if I have a more substantial change.

[lmeyerov]

can do, on it

.. pushed

@ZiyaoWei Can you review so we can merge?

[ZiyaoWei]

Not sure what you mean - the agent needs to query the server, right? Also - just to be clear, this line doesn't talk to the server AFAIK - it switches the backend to "server" so the agent does not query Prefect Cloud.

@lmeyerov I'm a bit confused by one comment but other than that looks good!
