Add host UTS namespace support for Add-Ons (#3596)
* Add host UTS namespace support for Add-Ons

Using the UTS host namespace is useful when running a mDNS responder
which learns the hostname from the gethostname syscall. This way the
add-on can use the system's hostname without further doing.

* Check host_uts default

* Adjust Security rating if host UTS mode and CAP_ADMIN is set

* Don't add hostname to DNS server if UTS namespace is disabled

* Simplify hostname logic

* Update supervisor/docker/addon.py
