Added Mirror support (#173)

If you want to use a mirror server, then with this you can override the server protocol and URL, e.g. on the command line by using ansible extra-vars.
Adding leading directories is possible if needed, but no trailing slash should be used.

The default-key for this feature has that form:
```yaml
visual_studio_code_mirror: "https://packages.microsoft.com"
```
