The agent string was inspired by the HTTP User-Agent header to serve as
a way to identify what's connecting to the cluster. While there may
have been vision of other software connecting to a controller than the
Clusterio provided ones this seems highly unlikely to ever happen.
Remove redundant agent string for now.
Refactor away the config group concept and simplyfy the way config
fields are defined. Fields are defined directly as properties of the
static field fieldDefinitions on the class itself with a separate
interface to declare the types of fields.
This makes it possible to easily make accessing the config fields type
checked in a way that lets plugins extend the interfaces with their own
config options by adding additional fields to the interface via
declation merging.
Refactor the Config and ConfigGroup classes to match the JSON data class
pattern with toJSON, toRemote and fromJSON methods replacing the load,
init, and serialize methods. Since fromJSON requires extra information
the messages structures passes around the plain JSON representation of
the configs instead of serialising instances of the config classes
automatically.
Move BaseControllerPlugin to controller/src/BaseControllerPlugin.ts
Move BaseInstancePlugin to host/src/BaseInstancePlugin.ts
Move BaseControlPlugin to ctl/src/BaseCtlPlugin.ts
Move BaseWebPlugin to web_ui/src/BaseWebPlugin.ts
This solves the circular package dependency problem of the base plugins
needing types that are available only in the dependencies to lib.
Be consistent with the usage of tabs as indents in all JSON files in the
project. This makes it easier to configure editors to emit the right
indents when manually editing these files.
