names: Store domains in kvstore instead of /etc/hosts
As reported in discussion forum[1], when clients connected via 'shared' network
connection try to resolve the a static domain name configured in FreedomBox,
they resolve to 127.0.1.1. Since this refers to client's own IP address, they
fail to connect.

In the previous version, this was not a problem because the entry was stored as
<hostname>.<domainname>. To resolve this, store domain names in kvstore instead
of /etc/hosts.

Tests:

- Adding/removing static domains from Names app works. The order of added
domains is preserved in the stored configuration. When adding a existing domain,
a proper error message is shown.

- Without the patch, configure multiple domains. They show up in /etc/hosts.
Apply the patches and restart the service. Names app setup will run. Entries
from /etc/hosts are removed and will be added to kvstore. The list of domains
shows properly in Names app. After restarting the services, domains are show
properly.

- Without the patch on a version of FreedomBox without support for multiple
static domains, configure a static domain. Switch to latest version FreedomBox
with the patches. Restart the service. Names app setup will run. Entry from
/etc/hosts will be removed and will be added to kvstore. The list of domains
shows properly in Names app. After restarting the services, domains are show
properly.
