Artf/cleanup post shell

[wild-endeavor]

Now that the first shell pr has been merged into master, we're doing some clean up work.

• Remove the inputs/outputs logic from the cloud publisher on the admin side and move it to the event handler on the artifact side
• Remove the initialization sql bit and made hstore extension creation just a migration
• Refactor the handler to be outside of the receiver in artifact events
• Add adminclient into the servicecallhandler object
• Set gizmo sqs config to false for consuming base64 and update the sqs processor to be roughly functional
• Fixing lint issues
• Add artifact configuration to the sandbox values file
• Infra related updates
  • Remove the old python artifact service helm templates
  • update local sandbox configuration to support routing back out to local development endpoint

@eapolinario maybe we can talk about the go mod change. I kept running into an error with go mod tidy, ended up resolving it by setting sigs.k8s.io/controller-runtime to a real version rather than the 00001000 version or whatever. but it's replaced anyways so i feel like it shouldn't matter. not sure what i was doing wrong.
