soroban-rpc: deploy public instance on futurenet

[mollykarcher]

What problem does your feature solve?

We'd like to facilitate more engagement/usage of RPC in the ecosystem prior to launching on testnet. We eventually plan to host a public instance on testnet as well, but not pubnet.

What would you like to see?

A deployed public instance of soroban-rpc on futurenet on stellar domain,rpc-futurenet.stellar.org. Deployment should be integrated into the soroban release process so that it receives updates appropriately.

Initial deployment to use k8s and the quickstart soroban-dev image for soroban rpc, and ingress route for dns.

This initial deployment will later be refactored to use new rpc service deployment image from #382 and updated helm chart to use/config that image.

What alternatives are there?

• Deployment Image for Soroban RPC #382 as a pre-requisite/blocker
• quickstart in its current form (potentially faster/easier, but to be followed up prior to testnet release by Deployment Image for Soroban RPC #382)

Are we sure this is a good precedent to set? I'd rather see deployments be as simple and streamlined as possible.

for stop gap, @leighmcculloch helped out, and did a short term deployment of quickstart(soroban-rpc enabled) on Digital Ocean:

@sreuland @tomerweller Do we need stellar-futurenet.4d63.com/ anymore?

[tomerweller]

no. we have rpc-futurenet.stellar.org

[willemneal]

@tomerweller Should we add this to CLI? Have a special futurenet network so you can do --network futurenet or SOROBAN_NETWORK=futurenet without having to manually add it?

[tomerweller]

@willemneal yes I like that idea!
