Integrate spring-tools, sts4

[oysandvik94]

Problem Statement

STS4 provides tooling for Spring Boot. Someone made it work for emacs, so I think it should be possible for nvim as well.

From this issue, it seems like there is an LSP that integrates with JDT ls, and also there is a TS client consuming some stuff.

Ideas or possible solutions

Since it looks like the sts4 lsp needs some integration code, I think this plugin is a good candidate to integrate it.

I would like to give it a try, I just need some time to figure out how to get started.

I'd rather not add framework/library specific extensions to nvim-jdtls.

I think it should be possible to add the extension without changing nvim-jdtls itself. From flying over the linked issue, it sounds like one'd need to:

• Configure the additional bundles (similar to how java-debug is setup, add the location of the jars to the bundles config option)
• Add some client commands. Neovim contains a registry for client side commands and you can inject commands there. It's a table under vim.lsp.commands, where the keys are the command names. (On nightly there are docs under :help vim.lsp.commands, they're unfortunately missing in the 0.9.x releases)

Thanks, I'll try to add it in a separate plugin. I received some pointers here.
