### Description
`CODER_AGENT_TOKEN` env variable was incorrectly being passed to the
curl command instead of the executed script during agent initialization.
Fixed the command order to ensure `CODER_AGENT_TOKEN` is properly passed
to the script execution context rather than the download command.
This pull request introduces support for external workspace management, allowing users to register and manage workspaces that are provisioned and managed outside of the Coder.
Depends on: https://github.com/coder/terraform-provider-coder/pull/424
* GET /api/v2/init-script - Gets the agent initialization script
* By default, it returns a script for Linux (amd64), but with query parameters (os and arch) you can get the init script for different platforms
* GET /api/v2/workspaces/{workspace}/external-agent/{agent}/credentials - Gets credentials for an external agent **(enterprise)**
* Updated queries to filter workspaces/templates by the has_external_agent field
* chore: refactor entitlements to be passable as an argument
Previously, all usage of entitlements requires mutex usage on the
api struct directly. This prevents passing the entitlements to
a sub package. It also creates the possibility for misuse.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* feat: Add trial property to licenses
This allows the frontend to display whether the user is on
a trial license of Coder. This is useful for advertising
Enterprise functionality.
* Improve tests for license enablement code
* Add all features property
