remsh should guess -name and -cookie on Windows

[wohali]

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.

Can I try this out?

@abyss143 Any open issue is available for someone to work on. Feel free to submit a PR!

AFAIK we do it already here https://github.com/apache/couchdb/blob/master/rel/overlay/bin/remsh#L41

@iilyak that's only cookie, not name, but could you look at #2738 ?

OK, this is now done for *nix platforms thanks to #2738 . We still need it for Windows.
