  To: pve-devel

to reduce code duplication and make it easier to add more options for
pool commands.

Use a new rados object for each 'osd pool set', as each command can set
an option independent of the previous commands success/failure. On
failure a new rados object would need to be created and that will
confuse task tracking of the REST environment.

Note:
    v1 -> v2:
	* reorder patches, since pool create & set share common pool
	  options.
	* include new setpool API
