mgr/dashboard: Dashboard breaks on the selection of a bad pool
If a pool is created with a wrong rule that is oversized for the cluster it gets into the "creating+incomplete" state.
This wont break the dashboard yet, but when clicking on the pool to get it's details every API request will be left unanswerd. The first unanswered call is "/api/pool/$badPool/configuration".
To reproduce this you can create an erasure code profile with a greater value for k than you have OSDs.
