Support to add project dependencies

[wandersoncferreira]

Is your feature request related to a problem? Please describe.
While working with clojure projects is common to include new libraries as dependencies. Right now, I am using clj-refactor to provide this functionality (https://github.com/clojure-emacs/clj-refactor.el/wiki/cljr-add-project-dependency) but would be nice to have this in clojure-lsp also.

Describe the solution you'd like
Same behavior as clj-refactor https://github.com/clojure-emacs/clj-refactor.el/wiki/cljr-add-project-dependency but without hot-reload.

Additional context
Something that clj-refactor does not take into account is to verify if a library already exists in your project. Therefore, if you try to include the same dependency more than one time, you will succeed. This could be a stretch goal to be fixed in this new version.

Thank you for the report!

It's a nice custom addition to clojure-lsp IMO, not so easy though. We'd need to create a custom LSP method for that that would request clojars/maven about the available artifacts and return to client so the client could ask for user which one use, after selected the client send again to server asking the available versions, which server requests again and return to client, then user selects the version, send to server and server make the proper changes on files.

I still need to check how clj-refactor requests clojars/maven and if that can cause any "too many requests" error.
