Fix bug 1151 to install openebs operator

This change updates the method install_k8s_storageclass of
full_install_osm.sh.

The change creates a temporary folder for downloading the K8s manifest
file for openebs. The download of the manifest file is decoupled from
its application with kubectl (in the same way that it isdone for the
CNI provider). After its application, an additional check is added to
verify that the storage class openebs-hostpath has been defined. If it
does not exist, the installation will fail and exit. Otherwise, it will
proceed. Finally, the timeout for the openebs-hostpath storage class
has been increased from 300s to 400s.
