1. Simplify this by leveraging the existing remove_osd/add_osd functions, since its task was functionally identical to those two in sequential order. 2. Add support for split OSDs within the command (replacing all OSDs on the block device(s) as required). 3. Add additional configurability and flexibility around the old device, weight, and external DB LVs.
