Multi product architecture (#3381)
- provides support for compiling Boards directly into the Mattermost suite server
- a ServicesAPI interface replaces the PluginAPI to allow for implementations coming from pluginAPI and suite server.
- a new product package provides a place to register Boards as a suite product and handles life-cycle events
- a new boards package replaces much of the mattermost-plugin logic, allowing this to be shared between plugin and product
- Boards now uses module workspaces; run make setup-go-work
