[RFC] Truly convenient SSH

[kovidgoyal]

Hi all,

I have redesigned the kitty ssh kitten with many new and powerful features. A quick summary:

• Specify local files and environment variables to automatically copy to the remote server when logging in, allowing you to setup your shell/editor as you like on the remote machine
• Automatically enables shell integration when logging in to remote servers
• Automatically uses SSH control masters so that new connections to the same host in the same kitty instance re-use the existing connection, avoiding connection setup latency
• Using new_window_with_cwd and launch --cwd=current and similar when the active window is an ssh kitten will automagically open a new window logged into the remote server at the current windows working directory
• Makes a kitty executable available on the remote host. The first time it is run it will download and install the real kitty automatically. Useful for running kittens such as icat or file transfer. Only works on Linux or macOS remote hosts since prebuilt kitty binaries are only available for those.

See https://github.com/kovidgoyal/kitty/blob/master/docs/kittens/ssh.rst for an overview of the new kitten and https://github.com/kovidgoyal/kitty/blob/master/kittens/ssh/options/definition.py for details on the various configuration options.

I would appreciate some testing/comments about the new functionality before releasing it. Thanks to @page-down it has already been tested with a variety of Linux, macOS and BSD servers. You can install nightly kitty builds to test: https://sw.kovidgoyal.net/kitty/binary/#customizing-the-installation

I have added functionality to have the ssh kitten install a kitty stub executable on the remote host that will automatically download and install kitty and run it, if invoked. This allows usage of kittens such as icat or file transfer on the remote host, seamlessly.

Added an option "color_scheme" to easily change terminal colors when connecting to a remote host. https://github.com/kovidgoyal/kitty/commit/dd331ca12efcb753ae3d8a6cce04d7c078601195
