I suppose this should be per-medium option.
Also it seems ok to allow any codec for non-vital data.

For non-vital data, RF=1 is the best option, I guess.

If we limit options just because data cannot be safely placed, then it is not an issue for data which don't have to be safely placed. Various codecs and replication-factor could be useful for performance aspect and/or for experiments.
For example: erasure codec provides more data-safety than RF=1 even when parts are stored on a single disk.

Let's do it in simple form -- support a global blacklist of forbidden erasure codecs. It should look like a field "forbidden_erasure_codecs", similar to this one.
Validation and its invocation points should be similar to this.
Use this original commit as an inspiration; though, its logic is more complicated (we do not need a logic for deprecation aliases, just the blacklist).
Also, similar integration test is required.
