This adds support for analysis domains that plugins contribute to by
sending notifications. I've only implemented folding so far, but most
of this CL is to cache results from plugins and to adapt sending server
capabilities.
Instead of using a NullNotificationManager, the LSP server now uses a
regular NotificationManager, except that results won't be forwarded to
clients. LSP handlers will fetch partial results from plugins and merge
them with data from the server that will be computed when needed.
I've extracted the server capabilities calculation from the init
handlers into ServerCapabilityComputer. It will also contain the
interestingFiles glob from active plugins and re-register capabilities
whenever plugins change.
