lsp: LSP should still suggest results even if import not present

[jeanbza]

If I start typing json., I expect to get results from all json packages (probably ranked/ordered somehow, with any imports being at the top). Pressing enter on a result from an unimported package should import that package.

However, LSP does not suggest results from anything you have yet to import. This greatly inhibits the code-complete functionality:

• First I have to go find the exact package of the thing I'm looking for (already the major purpose of code completion for me is lost)
• I have to manually add it
• I have to be careful not to save file in vscode, which will run goimports, which will remove my import because nothing uses it
• Perform auto-complete
• Save

This is not an ideal situation. It would be greatly alleviated if I could have just use autocomplete to search for the method I'm looking for across all packages.

I realize this is probably hard in a GOPATH-less world, FWIW.

We are working on this. See #31906.
