Provide namespace docstrings for eg. lsp-ui

[lassemaatta]

Is your feature request related to a problem? Please describe.

When using lsp-mode as the client and clojure-lsp as the server, there doesn't seem to be a way to display or browse namespace docstrings (like docstrings for vars).

Describe the solution you'd like

Given the namespace declaration below, and the cursor in the position represented with | => lsp-ui (or some other similar tool) should show the namespace docstring for clojure.test.

(ns some.namespace
  (:require [cloju|re.test :refer [deftest testing is]]))

@lassemaatta I can see that working with hover LSP feature, similar to when you ask for docs for a symbol, I think lsp-ui has features to show popups somewhere for that so maybe it'd work out of the box for you, I don't use lsp-ui anymore though so not sure
