Modules and plugins can only have one integration test target associated with them.
When there is a conflict between alias(es) and/or the target name, only one target will trigger on changes to the module or plugin.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* The module now correctly sets the timezone in both the config file and
in /etc/localtime; while hwclock is set in both the config and
/etc/adjtime.
* Module checks if the timezone is actually set by checking
/etc/localtime. Before it only checked if it was set in the config file.
* Fixed module not setting the timezone on RedHat systems if
/etc/localtime was a symbolic link.
* Fixed module failures in case of missing config files or incorrect data
in them.
* Added a lot of integrations tests to cover most of these situations.
* Handle timezone updates on Ubuntu 16.04+ on containers
Although Ubuntu 16.04 will use timedatectl by default,
containers without a working timedatectl need to use the
old method.
A bug in Ubuntu for the old method means having to write
a nasty hack

* Add tests for timezones
Ensure timezone changes work across various OSs
