Hervé Beraud 1fcb3e8acd Add a new type HostDomain. 
HostDomain is like HostAddress with the support of
_ character - RFC1033

openstack services are failing to start when a hostname with underscore
_ is provided.

Example:

```
overcloud-novacompute_edge1-0.internalapi.localdomain
overcloud-novacompute_edge1-0.internalapi
```

Nova use `HostAddressOpt` to define `live_migration_inbound_addr`,
and if a hostname with underscore is present in the config file
then the service fail to start.

Example:

```
/etc/nova/nova.conf
live_migration_inbound_addr =
overcloud-novacompute_edge1-0.internalapi.localdomain
```

FQDN is a domain name that specifies its exact
location in the tree hierarchy of the Domain Name System (DNS).

Underscore are allowed by RFC1033 [1][2][3]. Indeed, while a hostname may not
contain other characters, such as the underscore character (_), other
DNS names may contain the underscore.[1][2].
Systems such as DomainKeys and service records use the underscore.

These changes allow us to use underscore with the `HostDomain`.
