Marathon directory as a subdomain

[yurinnick]

Change default frontend Host value from foobar.marathon.localhost to foo.bar.marathon.localhost for Marathon apps with ID /foo/bar.

This will be a big win for us. We have apps in folders marked dev/test/staging/prod and right now front end looks like prod-xyz.com

Hi everyone, don't you think it would be even better to reverse the name like in: /foo/bar/myapp > myapp.bar.foo.{defaultDomain} ?

[darKoram]

We use wildcard certs and they only support single depth. So perhaps it could be an option which format you want. The extra depth of subdomains here we'll break our cert usage

[yurinnick]

@darKoram maybe you can set - as default delimiter, but leave an option to change it.

[yurinnick]

@darKoram another solution is using path like marathon.localhost/foo/bar for app with /foo/bar id. It's not so elegant, but still be better than now.

OK, I added an optional groupsAsSubDomains parameter in PR #426 :)
WDYT?
