Adrian Likins 2c7563b9bb Add modules for NetApp SANtricity storage platform (#2929)
The modules prefixed with netapp_e* are built to support the
SANtricity storage platform.

The modules provide idempotent provisioning for volume groups, disk
pools, standard volumes, thin volumes, LUN mapping, hosts, host groups
(clusters), volume snapshots, consistency groups, and asynchronous
mirroring.

They require the SANtricity WebServices Proxy.
The WebServices Proxy is free software available at
the NetApp Software Download site:

   http://mysupport.netapp.com/NOW/download/software/eseries_webservices/1.40.X000.0009/

Starting with the E2800 platform (11.30 OS), the modules will work
directly with the storage array.  Starting with this platform, REST API
requests are handled directly on the box.  This array can still be
managed by proxy for large scale deployments.
