Background

We are in the process of consolidating/refactoring the API calls the Coder Agent makes into a new Agent API. This API will be versioned separately from the main Coder Product version and consist of a major and minor version (no patch).

The existing combination of REST calls and websockets is now defined as Agent API version 1.0.

Feature

1. Define a new column in the workspace_agents table, called api_version to track the API version of the agent when it connects.
2. Populate the API version in the same code-path as we populate the version column. For now we can hard-code 1.0 as the version.
3. API calls that fetch the Agent should return the api_version.
