[Feature] Add openstack provider

[alexandrevilain]

Adding openstack provider will allow us to use great providers like OVH providing instances starting à 0,008€/hour.

I can work on it, submitting a PR on inletsctl.

Expected Behaviour

Adding the --provider openstack flag should provision a new instance on an openstack provider.

Current Behaviour

We can't provision an instance on providers using OpenStack.

Possible Solution

Using gophercloud: https://github.com/gophercloud/gophercloud
And adding the following flags:

• openstack-endpoint
• openstack-username
• openstack-password

Interesting suggestion, I'd like to know more. Do all providers expose openstack directly? I don't think that Civo does that, they wrap it with a ruby REST API.

Are all instance names and images the same between every openstack deployment?

I'd think you may need more parameters, but I'm not an openstack expert.

Hi @alexellis! Sorry for the delay.

I don't know which provider exposes the OpenStack API. The only provider I know is OVH which exposes the OpenStack API. I think that instances types and images are different between providers. So you're right, I'll need more parameters.

I'm now working on EC2 provider, I'll start working on OpenStack after that. I think that I'll have more work to do as we will need to pass more parameters to the provider.

Hi @alexellis
I think that I can take inspiration from the terraform openstack provider.
There are many parameters: https://github.com/terraform-providers/terraform-provider-openstack/blob/master/openstack/provider.go
