* Removing alpha disk from tests.

* Changes setup the test to run with hyperdisk extreme.

* Updates the disk type back to balanced, as HDX doesn't support multi writer.

* Moving over to m1 megamem as thats the only type of machine that can support all needed disk types.

* Changes update the tests to use two contexts, one for multiwriter and one for the existing tests. This was deemed necessary as only some disks can support multi-writer, and only some VM shapes can support said disks.

* Changes update the tests to use two contexts, one for multiwriter and one for the existing tests. This was deemed necessary as only some disks can support multi-writer, and only some VM shapes can support said disks.

* Fixing some git oddness

* Fixing some formatting.

* More formatting fixes.

* Hopefully last changes for formatting.

* Fixing linting issue.

* Cleaning up un-used / un-needed GetMultiWriter test function.
