Introduce the CommandExecutor interface to abstract command execution,
allowing for easier mocking in tests. Implement DefaultCommandExecutor
to use the os/exec package for executing commands. Update the
GenerateCosmoRouterConfig function to utilize the new
GenerateCosmoRouterConfigWithExecutor function that accepts a command
executor parameter. Add a MockCommandExecutor for simulating command
execution in unit tests with realistic behavior based on input YAML
files. This enhances test coverage and simplifies error handling.
Implements the `latestSchema` query to fetch the latest schema
updates for an organization. This change enhances the GraphQL API by
allowing clients to retrieve the most recent schema version and its
associated subgraphs. The resolver performs necessary access checks,
logs relevant information, and generates the Cosmo router configuration
from fetched subgraph SDLs, returning structured schema update details.
Creates a new `GenerateCosmoRouterConfig` function to build and
serialize a Cosmo Router configuration from subgraphs. Implements
PubSub mechanism for managing schema updates, allowing
subscription to updates. Adds Subscription resolver and updates
existing structures to accommodate new functionalities. This
enhances the system's capabilities for dynamic updates and
configuration management.
