Apply defaults when a plugin fetches the config

[mattermod]

Plugins may specify a schema for their configuration in plugin.json, e.g. https://github.com/mattermost/mattermost-plugin-demo/blob/4e6fa3aa03bc58d62d1ceb3207c293d6641ea12a/plugin.json#L17. This schema optionally specifies default values, but currently don’t get returned when the plugin asks for its own configuration.

Change GetConfig and GetUnsanitizedConfig – and implicitly GetPluginConfig – to apply these default values as specified in each plugin’s manifest. Of course, if a plugin has been configured, the default value will be ignored.
