How to use/run space cloud's gateway binary as a standalone component.

[sharadregoti]

Context...
Space cloud's current architecture uses two components

• Gateway
  Responsible for handling request response of database, eventing, filestore, ingress routes, remote service.
• Runner
  Responsible for handling request response of secrets & deployments feature. This component interacts with Kubernetes.

A developer might want to use graphql API provided on top of databases and services or use the eventing module. In these cases, the runner component is an overhead with no use.

Space cloud should mention these in docs or make a guide around it.
