Removed generic scripts without functional tie to AppMetrics.

This pull request supersedes and thus closes #105.

@mrdavidlaing - Given the release of the [AWS Tools for Windows PowerShell](http://aws.amazon.com/powershell/) I think we should base our Windows specific scripting solely on this approach, which renders those scripts originally queued for migration to https://github.com/cityindex/labs-operations obsolete in their current form at least.

I've started documentation on how to achieve the same goal via PowerShell in [
Scripting instance operations via PowerShell](https://github.com/cityindex/labs-operations/wiki/Scripting-instance-operations-via-PowerShell) - the documented  'one liners' could still be converted into respective scripts again to improve usability, i.e. ease usage by calling a dedicated script for specific every day operations like a red button stop of a particular instance set.

If you agree, this pull request could be merged.
