Feature request: assign host to Inventory group

[m8ram]

This replaces the same feature request in the insights ansible collection RedHatInsights/ansible-collections-insights#88

Now that Inventory Groups are live the ansible role should allow the user to set the Inventory group.

To be clear the goal is not to use the current --group=GROUP option of insights client which adds a tag but does not add the system to an Inventory Group.

This depends on RedHatInsights/insights-client#156 being resolved first.

This should use the --workspace terminology instead.
