Making TRAMP faster

I kinda gave up on using it because so many of my remotes are tunneled through a jump host and I never could get it to connect seamlessly. It seems like it ought to, but when vscode just works with my ssh config, I decided debugging it was not a good use of my time. Might have something to do with being on a Mac, idk.

I found that setting (customize-set-variable 'tramp-use-connection-share nil) made things "just work" with my .ssh config (the documentation for that variable seems to imply this is expected).

If you still want connection sharing, you'll have to set it in your .ssh config, but it works without it.
