teuthology erasure coded pools : warning

Hi,

TL;DR: if teuthology ec_pool workloads break, ping me or check https://github.com/ceph/teuthology/pull/271 for errors

A new way of creating the erasure coded pools in teuthology was merged a few hours ago https://github.com/ceph/teuthology/pull/271
It has not yet been tested and should not introduce any change. But it has not been tested for real and there is room for error. There is a potential for breakage for every workload containing ec_pool: true in the yaml description.

The general idea of the change is to replace hardcoded parameters with erasure code profiles read from the yaml file, with a default profile that matches the former parameters defaults.

Cheers

After some manual testing, it needs https://github.com/ceph/teuthology/pull/277 to run. If not applied existing ec_pool workloads will fail.
