awesomewm terminal

I'd love to implement this:

```lua
local Terminal = require'toggleterm.terminal'.Terminal

local function close_terminal_on_zero_exit(terminal, _, exit_code)
if exit_code == 0 then
terminal:close()
end
end

local lazygit = Terminal:new({
cmd = 'lazygit',
direction = 'float',
hidden = true,
on_exit = close_terminal_on_zero_exit,
})

local dotfileslazygit = Terminal:new({
cmd = 'lazygit --git-dir=$HOME/.cfg --work-tree=$HOME',
direction = 'float',
hidden = true,
on_exit = close_terminal_on_zero_exit,
})

wk.register({
G = { function()
if vim.loop.cwd() == vim.call('expand', '~/.config') then
dotfileslazygit:toggle()
else
lazygit:toggle()
end
end , 'lazygit'},
}, { prefix = 'g' })
```
