Move Timeout, Name, and Group to CommandOptions

[dahernan]

I'm thinking of moving the methods Timeout(), Name(), and Group() to CommandOptions and keep the Interface simple.

You can pass the options to the NewCommand as following

NewCommand(interface, commandOptions, circuitOptions)

@zeisss any advice??

I would veto that IMHO. My preference would still be having something I described in #6.

Reasons:
The author of the commands has better insights into the needed circuitbreaker options than a "user" of the commands (The commands could come in library and are just used a client-lib by some other service).
Also I don't want to copy&paste the options-creation code-snippet to every place that initialized the command (the same command could be used at multiple places).

We maybe should make a list of all the options we have first - I was just thinking that we may want to set certain options like the circuitbreaker globally and not per-command?

How is the circuit breaker currently found/shared? Per group+command-name?
