Add get_selections() and set_selections() for dpkg.

This module will enable to freeze a package at a certain version, with the "hold" state.
Add TODO, amend later... FIXME.
possible fix for https://github.com/saltstack/salt/issues/5567
possible fix for https://github.com/saltstack/salt/issues/5567
Removed unnecessary os_family mappings for pidora
Update host/ip pairing rather than add the hostname a second time
Added replace kwarg whether to first remove any existing hostnames that match
Avoid running qemu-img when hypervisor is specified as esxi.

This is shown in the logs before this patch:

```
qemu-img: Could not open '[0] vm1/vm1.vmdk': No such file or directory
```

And the result from running virt.get_disks vm1 was before this patch:

```
build04:
    ----------
    sda:
        ----------
        file:
            [0] vm1/vm1.vmdk
        image:
            Does not exist
```

After the patch is applied:

```
build04:
    ----------
    sda:
        ----------
        file:
            [0] vm1/vm1.vmdk
```
Remove print()
Unify name: emulator vs hypervisor

Include secondary IP addresses in ip_addrs{,6}

These functions were not iterating over the list of secondary IP
addresses, causing grains['ipv4'] and grains['ipv6'], as well as the
module execution functions network.ip_addrs and network.ip_addrs6 to
fail to include these IPs. This commit fixes that oversight.
