Commit f977b8a while dropping all python dependencies also dropped
floaterm. However it has a dependency on python based neovim-remote
only if integration with git or floaterm is required from command line
which we do not. So add it back. Using the previous toggle bindings
with this gives a nice floating terminal which can be easily hidden.
