The Hybrid UI symfony prototype relies on the admin being accessed via a siteaccess (http://example.com/admin).

The admin siteaccess(es) should be automatically defined, while allowing configuration and customization.
Special settings, such as languages, must be searched for use-cases and covered.

For now, one admin siteaccess is generated per siteaccess group, assuming that one group matches one repository (we need a separate admin siteaccess per repository because of settings). If there is only one group, the admin siteaccess is named admin. If there are several, they are named admin_<siteaccess_name>.

Open questions:

• when there is one siteaccess, how is the admin siteaccess named ?
• where there are several siteaccesses, do we generate one or several admin siteaccess ? Do we add options for that ? How is each siteaccess named ?
• how is the admin siteaccess matched when host mapping is used ?
• how is the admin siteaccess matched when port based mapping is used ?
