osd: add pg autoscaler support This commit adds the pg autoscaler support. The structure for pool definition has now two additional attributes `pg_autoscale_mode` and `target_size_ratio`, eg: ``` test: name: "test" pg_num: "{{ osd_pool_default_pg_num }}" pgp_num: "{{ osd_pool_default_pg_num }}" rule_name: "replicated_rule" application: "rbd" type: 1 erasure_profile: "" expected_num_objects: "" size: "{{ osd_pool_default_size }}" min_size: "{{ osd_pool_default_min_size }}" pg_autoscale_mode: False target_size_ratio": 0.1 ``` when `pg_autoscale_mode` is `True` user has to set a decent value in `target_size_ratio`. Given that it's a new feature, it's still disabled by default. Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1782253 Signed-off-by: Guillaume Abrioux <gabrioux@redhat.com>
