Issue 50534 - CLI change schema edit subcommand to replace
Description: The way the CLI currently edits an attribute or objectclass
is that it deletes it, and then adds the new attribute using
only the params specified in "edit". So the subcommand "edit"
is misleading as previous/untouched values will get overwritten,
it should be "replace" instead to avoid confusion.
