- This change adds two types to support opaque runtime
data passing through the APIServer:
- RuntimeConfiguration `data`
- RuntimeLinuxData type
- LinuxRuntimeData defines runtime specific information.
With this change, it will support `variant` only. The
optional RuntimeConfiguration `data` field encodes
runtime specific data to pass through the APIServer.
It is decoded as needed by the runtime.
- The idea is to eventually move all runtime specific data
into the `data` field so that the APIServer is only aware
of generic container information.
- Part of #1318.
- Part of #1378.
- `RouteHandler` now accepts an additional `XPCServerSession` which
include a disconnect handler.
- `XPCServer` configures a session for each client connection and passes
it to every route handler.
- `XPCServer.route(fn:)` can be used to wrap existing route handlers
that don't care about sessions.
- `XPCClient` adds functions to support client-side session handling.
- Update all existing routes.
This change migrates plugin config format away from using JSON to use
TOML.
- Addresses the plugin portion of discussion #1336

## Motivation and Context
Context within https://github.com/apple/container/discussions/1336
> We're looking to improve the user experience and overall functionality
of setting defaults for container to better enable future use cases.
>
> Today container uses macOS's
[UserDefaults](https://developer.apple.com/documentation/foundation/userdefaults)
to configure settings needed at runtime. As mentioned in
https://github.com/apple/container/issues/608, UserDefaults may be
idiomatic for macOS, but they apply globally to all sessions and do not
handle representing complex, hierarchical data well. Additionally, we
currently have two ways of setting these defaults, either directly with
macOS's defaults command or through container system property.
>
> https://github.com/apple/container/issues/608 proposes moving to use
environment variables in place of UserDefaults. However, we do not
believe this is sufficient. Environment variables are not in a
consistent location, are not sourced from data, and also do not handle
representing complex, hierarchical data well.
As part of this migration to TOML for user settings we want to also move
plugin settings to use TOML so that we can have a singular file format
for `container` configurations.
