mgr/dashboard: slashes in RBD pools and RBD images
2 - major
Pull request ID:
While Ceph allows pools to be named with any UTF-8 symbol, including "/", we are explicitly banning those from RBD-tagged pools:
- We don't allow to create a Pool named "Hello/world" and be tagged as RBD.
- If such a pool was created by CLI, we don't allow any edits on it, neither do support creating RBD images.
This has been reproduced in Nautilus and master but probably happens in Mimic as well.
