remsh should guess -name and -cookie on Windows

## Summary

`remsh` could easily be enhanced to guess at the correct value for the node name and Erlang cookie, for the CouchDB running on the current host.

## Desired Behaviour

Type `remsh` on a machine that's running CouchDB, and it should automatically self-configure so that it can connect to the locally running node.

## Possible Solution

Use `grep` (or a similar Windows function) to search the `vm.args` file for the `-name` and `-cookie` arguments. Use those as default parameters, if alternatives have not been specified on the `remsh` command line.

## Additional context

Operator happy fingers are important. Being able to type `remsh` on a machine and immediately be at the Erlang REPL is super valuable.

Start by locating the Windows implementation or entry point for `remsh` and how it handles command-line `-name` and `-cookie` options. Then inspect the CouchDB `vm.args` file handling; the work is done when bare `remsh` can use those values on the current host while explicit command-line alternatives still take precedence.
