Code Issues Proposed changes

Rely on ceph.conf settings when cinder backup pool is created

Browse Source 
Ceph adds the osd pool default size option on ceph.conf via [1];
this means we don't need to specify the size of this pool if
the same value (same variable) is used (CEPH_REPLICAS).
This change is an attempt of removing the size setting, relying
on the implicit declaration of the value provided by ceph.conf.
