https://issues.redhat.com/browse/XCMBU-122 brings in the support for editing / removing the default machine pool. The detailed PM requirements are here: https://docs.google.com/document/d/1yvPg6HFHL6Bwlsq7jqOcdHGHLN0z4qHisekMm8f24pw/edit#

In general, the ask is to modify the day2 machine pool experience so that:

1: it will be possible to change the instance type of the default machine pool

2: it will be possible to delete the default machine pool

3: it will be possible to scale the default machine pool to 0

4: it will be possible to add/edit taints and labels on the default machine pool
