Subject: [PATCH] Add a new element hpdsa

This element enables creation of Ubuntu deploy ramdisk and
user images which could be used to deploy the HP Proliant
Servers with Dynamic Smart Array Controllers. Without this driver
the disk with the Dynamic Smart Array Controller is
not visible to the ramdisk.

Closes bug: #1492803

+=====
+hpdsa
+=====
+This is the hpdsa element.
+
+This element enables the 'hpdsa' driver to be included in
+the ramdisk when invoked during ramdisk/image creation.
+
+This driver is required for deploying the HP Proliant Servers
+Gen9 with Dynamic Smart Array Controllers.
+
+Note: This element supports only Ubuntu image/ramdisk to be
+updated with the hpdsa driver. It installs hp certificate
+from https://downloads.linux.hp.com/SDR/hpPublicKey2048_key1.pub.
+Since HP has released this currently only for trusty,
+It has been restricted to work only for trusty.
