Code Issues Proposed changes

Use FQDN for MGMT network

Browse Source 
The management network is used extensively for all internal
communication.
Since the original use of the network was a private network before
it was exposed for external communication in a distributed cloud
configuration, it was never designed to be reconfigured.

To support MGMT network reconfiguration the idea is to configure the
applications to use the hostname/FQDN instead of a static MGMT IP
address.

In this way the MGMT network can be changed and the services and
applications will still work since they are using the hostname/FQDN
and the DNS will be responsible to translate to the current MGMT
IP address.

The use of FQDN will be applied for all installation modes: AIO-SX,
AIO-DX, Standard, AIO-PLUS, and DC subclouds. But given the
complexities of supporting the multi-host reconfiguration,
the MGMT network reconfiguration will focus on support for AIO-SX
only.

The DNSMASQ service must start as soon as possible to translate
the FQDN to IP address.

Test plan ( Debian only )
 - AIO-SX and AIO-DX virtualbox installation IPv4/IPv6
 - Standard virtualbox installation IPv6
 - DC virtualbox installation IPv4 ( AIO-SX/DX subclouds )
 - AIO-SX and AIO-DX installation IPv4/IPv6
 - AIO-DX plus installation IPv6
 - DC IPv6 and subcloud AIO-SX
 - AIO-DX host-swact
 - DC IPv4 virtualbox with subcloud AIO-DX and AIO-DX
 - AIO-SX to AIO-DX migration
 - netstat -tupl ( no services are using the MGMT IP address )
 - Ran sanity/regression tests
