OpenDev Migration Patch
This commit was bulk generated and pushed by the OpenDev sysadmins
as a part of the Git hosting and code review systems migration
detailed in these mailing list posts:
Attempts have been made to correct repository namespaces and
hostnames based on simple pattern matching, but it's possible some
were updated incorrectly or missed entirely. Please reach out to us
via the contact information listed at https://opendev.org/ with any
questions you may have.
This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.
This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.
This update should result in no functional change.
The update_hosts_file function requires a full map of entries to
write into /etc/hosts; the previous use of this function tried
to write individual host entries only.
Ensure that a full map of self + peers is written at appropriate
points in a units lifecycle to ensure self and peer hostname
resolvability.
Due to oddities in the way that DNS used to work on older MAAS
versions, specifically when using LXC containers, the charm
would endeavour to discover a full forward/reverse resolvable
hostname/ip address to use when clustering with peers, and to
set the internal nodename for each RMQ instance.
Changes in MAAS 2.0 mean that an IP address may resolve to more
than 1 DNS record, making identification via DNS of the FQDN
problematic.
The charm actively manages /etc/hosts with IP address/hostname for
all peer units in a RMQ cluster using the cluster relation; make
use of this feature to allow the internal nodename of each unit
to actually be the hostname of the server, as the charm is ensuring
the resolvability of hostnames within the cluster.
To avoid races where the lead unit has not had its hostname written
to /etc/hosts, only cluster with the lead unit in the hook execution
where this actually happens.

Closes-Bug: 1584902
(cherry picked from commit 7ffdcd204e6550cf5dcad57ed07ea302c1eedcce)
Change to is_ip to correctly detects both IPv4 and IPv6 addresses,
resolving problems when Juju presents an IPv6 based private-address
back to the charm.
Avoid use of 'service --status-all' which is currently
broken on trusty for upstart managed daemons; the change
moves to detecting how the daemon is managed, and then
using upstart status XXX or the return code of service XXX
status to determine whether a process is running.
Fixes for IPv6 network address detection under Ubuntu
16.04 which changes the output format of the ip commands
slightly.
Update the version map to include 8.1.x as a Neutron
version for Mitaka.
