config : Remove IE options

[ivanimanishi]

This PR removes the IE-specific config files, as they are now maintained in a separate internal repository.

Note that I don't think there is any need to update the Changes file, since there is not relevant code updates in gaffer itself, but let me know if you think otherwise.

Now using "black" style (in use at IE)

I'm not sure how I feel about this. I know this file is only for use by IE, but it's in the Gaffer repo, so I kindof think it should use the Gaffer conventions. Maybe you'd prefer to host it outside the repo anyway?

We are no longer reading those files directly from the gaffer repository when building gaffer at IE. We have them in a separate internal repository, which needs to match our coded style. My understanding is that the only reason now to keep it in gaffer itself is as an example for other about how to potentially run a custom install of gaffer.

I'm fine with either removing them completely from the gaffer public repo or updating them to their current IE state (this PR), black style and all (I don't want to go through the trouble of reformatting our internal options files to match gaffer's style).

What do you prefer?

[johnhaddon]

Oh, cool. If you don't need the file then let's just remove it. The CI setup still provides some examples on how to configure a build, and is probably a bit easier to follow.

Updated the PR, as discussed, to remove the config/ie files.
