Subject: [PATCH] nvim: Add nvim-dap configuration

Automatically opens dap-view when in debugging session (and closes when
done), sets some breakpoint jump logic and makes the gutter symbols
nicer.

Adds keybinds for most of the dap operations with
`<localleader>d<something>` where something is the operation (i.e. `c`
for continue, `b` for breakpoint and so on).
