Using SSH backend without ssh-agent

[marcy-terui]

Hi,

I want to run libspecinfra on CI services (e.g. Circle CI) and FaaS (e.g. AWS Lambda).
These services may be difficult to use ssh-agent.

So, I would like to implement the another way to use SSH backend that specify the host, user and key file or password.

@mizzy What do you think about these options?

First,

1. Change SSH backend to be able to use without ssh-sgent
2. Add a new backend
3. Any ideas?

Next, (Only if we choice 1 at first)

1. Change the argument of the backend_ssh_new cffi interface to a structure. This is very simple. But it has a breaking change.
2. Add a new cffi interface.
3. Any ideas?

Thanks for your proposal.

This one is best.

Change the argument of the backend_ssh_new cffi interface to a structure. This is very simple. But it has a breaking change.

We don't need to care backward compatibility currently. So this idea is good.

I'm glad to hear that. Thanks!!
