THORN-2445: old groupId org.wildfly.swarm.cli
THORN-2445: old groupId org.wildfly.swarm.cli

Motivation
----------
During the 2.5.0.Final release, I found that we still have
one artifact with old `groupId` of `org.wildfly.swarm.cli`.
It's been like that since 2.0.0.Final, but we should fix it anyway.

Modifications
-------------
Changed `groupId` from `org.wildfly.swarm.cli` to `io.thorntail.cli`.

Result
------
Everything Thorntail will be deployed under `io.thorntail`.
