moved to a format string 'erasurce-coded', that allows also to drop
most of the param existence checking as we can set the correct
optional'ness in there. Also avoids bloating the API to much for
just this.
Reuse the $rados connection more often to avoid to much
overhead/lingering sockets (the rados connection stays around in the
background to allow efficient reuse)
really should be three separate commits, but too intertwined and too
late for me to care tbh.

To use erasure coded (EC) pools for RBD storages, we need two pools. One
regular replicated pool that will hold the RBD omap and other metadata
and the EC pool which will hold the image data.
The coupling happens when an RBD image is created by adding the
--data-pool parameter. This is why we have the 'data-pool' parameter in
the storage configuration.
To follow already established semantics, we will create a 'X-metadata'
and 'X-data' pool. The storage configuration is always added as it is
the only thing that links the two together (besides naming schemes).
Different pg_num defaults are chosen for the replicated metadata pool as
it will not hold a lot of data.

When removing a pool, we check against any storage that might have that
pool configured.
We need to check if that pool is used as data-pool too.

this was from the time where we had a loop here to add two storages,
one for KRDB-only and one for KRBD-never. Nowadays we can handle the
mixed case just fine, but the patch dropping that forget to cleanup
the error handling..

In Ceph Octopus the device_health_metrics pool is auto-created with 1
PG. Since Ceph has the ability to split/merge PGs, hitting the wrong PG
count is now less of an issue anyhow.

the properties target_size_ratio, target_size_bytes and pg_num_min are
used to fine-tune the pg_autoscaler and are set on a pool. The updated
pool list shows now autoscale settings & status. Including the new
(optimal) target PGs. To make it easier for new users to get/set the
correct amount of PGs.
