Plugins

[bentsherman]

Nextflow plugins can provide additional config settings, functions, operators, and channel factories. In order for the language server to provide code intelligence for plugins, it needs to:

1. Retrieve the list of included plugins from the "main" config file
2. Fetch plugin metadata from either (1) the plugin downloads folder (i.e. using Nextflow's plugin system) or (2) some index file which is produced by the plugin build and published to the plugin registry
