Add custom resource for installing the Web UI.

/cc @sh9189 @acaiafa

Fixes #297.

This was definitely something that was missed from 2.0.

[Ginja]

Consul agent now has a built-in UI config flag:

https://www.consul.io/docs/agent/options.html#_ui

Should we be leveraging it instead?

[johnbellone]

Isn't the flag the same as writing config?

[Ginja]

I think it's built-in now (i.e. doesn't require a separate download). I may be misreading the docs though.

[legal90]

@Ginja You are right. Since v0.6.1 Consul UI is built-in: hashicorp/consul#1543
So, it isn't necessary to deploy a UI separately (thus it is still supported).

@johnbellone In few words there are two different config options (and CLI flags):

• ui. Being set to true, it enables the built-in UI.
• ui_dir. It configures Consul to use a separated Consul UI installed to the specified path.

I think it is reasonable to change default recipe a little bit. If I set ['consul']['config']['ui'] = true, I want to use the built-in UI, not the separated one.

[rossedman]

Has anyone else here tried to use the new cookbook with just setting ui to true? I am receiving errors when doing that. I think its great to use the internal UI unless customizing. Just looking for some feedback.

{
    "consul": {
        "config": {
            "ui": true
        }
    }
}
