`ceph_fs` deprecation message on clusters newer than 1.28

[BBBmau]

Description

Fixes #2406

Usually we would mark any fields as deprecated with Deprecated along with a summary, however this isn't the best UX since any use of the deprecated field will cause a message to pop up, ideally this would only pop up on clusters newer than 1.28

Currently looking for how to make this possible

@appilon this was something that did come to mind but wasn't sure if it was a valid reason to move the whole Create/Update functions in order to get it working. I'll try it out and see what happens!
