Add outputMode to configurations (#109)

nvim-dap had a change to log stdout/stderr of debug adapters to log
files instead of redirecting it to the repl.
(See mfussenegger/nvim-dap#1405)

delve by default outputs print statements on stdout instead of using
output events, which means they're no longer visible.

Setting `outputMode = "remote"` in a configuration causes delve to use
output events, which nvim-dap shows in the repl
