mgr/dashboard: Timeouts for rbd.py calls
As the corner cases are not implemented in many rbd.py methods, they can fail without a response on a specific pool (mostly bad pools).
If this is implemented remove the workaround that was implemented to fix #43765.
For details what known issue exists see #43771.
For details about the discussion that was made look at the PR that fixed #43765.
Make sure that #43771 is still not addressed before starting with this issue.
