Erlon R. Cruz f33b234aa0 Make scheduler check online_extend_support capability

Since Pike release, Cinder supports volume online extending, and by
default it assumes that every backend supports this feature. This
assumption causes a bug on those backends that don't support it. On
such backends, an online extending attempt leaves the volume in
error_extending state.

This patch allows a backend to report to the scheduler if it does not
support online extending. This way, an online extending attempt will
fail, without leaving the volume in error_extending state.
