Allows sub-uri deployment

[ares]

With this patch you can install foreman to sub-uri like this

foreman-installer --foreman-foreman-url="https://example.com/foreman" --foreman-proxy-foreman-base-url="https://example.com/foreman"

This doesn't sound logical.

Yes, but it's only way it works. I think it's caused by our hack in https://github.com/theforeman/foreman/blob/develop/config.ru#L6 - we set the prefix manually (so we can run development server under suburi) so having this set to /foreman would end up in double prefixing.

Looks very strange, but works perfectly, thanks @ares. Could you write a couple of tests for it? The URI parsing in the manifest is my main concern, I think that could quite easily be covered to ensure for a certain version of foreman_url that the httpd template is rendered in a particular way.

[ares]

@domcleal I added few tests. They do not directly test the parsing, I check content of the vhost config file. I didn't find any better way to test variable values if they are not used as a class parameters. Let me know if you have better idea how to do this.

[domcleal]

Nope, you're spot-on, you can only test the end resources.

Merged as 4cad220, thanks @ares!
