Rename DetachByDropletID function to Detach

[xmudrii]

This PR renames function detach-by-droplet-id to detach. Providing Droplet ID is as of April 4th, 2017 required and it's not possible to detach without anymore.
detach-by-droplet-id is long for a function and makes its usage inconvenient.

This PR also regenerates mocks as it was forgotten in #208.

@xmudrii I think we're better off having detach and detach-by-droplet-id both for now and just print a deprecation warning when detach-by-droplet-id gets called so people have some time to update.

[xmudrii]

@mauricio good reasoning, I agree on it. I will update PR to add Detach function and update DetachByDropletID to do the same, but just with depreciation warning. I would like to check is it okay to print warning to output or just to include deprecated in command description?

[mauricio]

We can just include deprecated at the description.

[xmudrii]

@mauricio is it good this way? 💯

[mauricio]

I think we should instruct people to use detach, so instead of just (depecated) use (deprecated - use detach instead).

[xmudrii]

@mauricio yep, I agree. Change pushed 😄
