* Add extra bootstrap flags, will need to parametrise these at some point
* ensure nodes are tagged when they are newly created
* assign the same ip suffix on the hypervisors for consistency
* Add partitioning, so that it's consistent with how
customer is doing it, so that replication of env is
a lot easier
* Start some work towards DNS names for VIPs and such
* Move the commision_vm/node to functions.sh
* if machine already exists in maas, then re-use it
* move node variables above the node_num, to calculate correctly
* Add comments to the default.config file
* move the node_count to the default.config, this will allow to use
customised value if needed
* If pod-console-logging tag is to be added, then add correctly,
Otherwise, if we are adding fresh pods after tag creation, the pods
will fail to add. This also allows for other cases to be fulfilled if
required
* Make password and virsh user consistent on hp01
* Update the config to reflect the network config from hp01
* Add timezone and byobu config in cloud init
* Add pod creation, so that when we remove the hypervisor
then all the VMs also get removed automatically
* virtinst is only used when creating/installing VMs, so
only install on hypervisor nodes
* Only grab the top vlan if we have 2, this typically
means that we have an ipv4 and ipv6 IP. Could probably
do this better, but keep it simple for the time being
* Move stuff from common to default, as it didn't make sense
* use virsh_user instead, that was its more customisable
* Revert the change to manage-maas-nodes.sh now use extra function to
call maas_auto_assign_networks instead
* More comments to the code
* Move all configs into config directory
* Move all examples into example directoy
* Move all common functions into functions.sh
* Fine tune a few other functions
* Moved common hypervisor config away
* Added examples for some of the hypervisor configs
* Start work on snap enablement of boostrap-maas.sh script
