Fix marathon groups subdomain

[emilevauge]

Fix marathon groups subdomain management.

Added new optional groupsAsSubDomains:

# Convert Marathon groups to subdomains
# Default behavior: /foo/bar/myapp => foo-bar-myapp.{defaultDomain}
# with groupsAsSubDomains enabled: /foo/bar/myapp => myapp.bar.foo.{defaultDomain}
#
# Optional
# Default: false
#
# groupsAsSubDomains = true

If enabled, instead of:
/foo/bar/myapp => foo-bar-myapp.{defaultDomain}
we now have:
/foo/bar/myapp => myapp.bar.foo.{defaultDomain}

Fixes #169

The StructTag is useless ...
I think I forgot to remove this one...
@emilevauge : Can you delete it ?

Indeed ;)
