Implements address space cleanup when a workspace service is uninstalled

[JC-wk]

Resolves #4727

Draft PR

This is in draft because

• unit testing may be needed
• I have noted an edge case of the address being released during a failed uninstall and then allocated elsewhere. I need to move the deallocation process to run after the main step has succeeded so it runs after the terraform uninstall. I am testing doing this in the service_bus now and it is working ok.
• To allow other to try this out and comment on it

What is being addressed

Currently address spaces are not cleaned up when a workspace service is uninstalled from a workspace, this could lead to ip range exhaustion.
This PR adds the functionality to delete the address_space used by a workspace-service on uninstall of the service. The address range is then freed from the workspace and can be reused.

How is this addressed

• Adds a step to the api to delete the address space when a workspace service is uninstalled
• Updates templates to conduct a workspace upgrade after uninstall
• I have not added any tests but happy to accept advice on how to implement these
• Updated documentation
• Updated CHANGELOG.md
• Increment template versions

I have been testing this for a few days, I am not sure if unit tests are needed and how best to write them if anyone wants to assist.
