[SRU] support SSH key value over fingerprint for Azure

[Ben Howard]

SRU JUSTIFICATION

[BACKGROUND] Azure's meta-data source now supports the use of SSH key values in addition to fingerprints.

[IMPACT] Instances booted with out cloud-init support for SSH public key values will be inaccessable on boot via SSH.

[FIX] Backport of 15.10 SSH public key support. Starting with 15.10, cloud-init supports both values (preferred) or generating the SSH public key from a fingerprint.

[TEST CASE]
- Update cloud-init from proposed
- Capture instance
- Create instance using SSH fingerprint, confirm instance is accessible via SSH.
- Create instance using SSH public key value, confirm instance is accessible via SSH.
- Create instance using both SSH fingerprint and a different SSH public key value. Confirm that the instance is accessible via SSH only with SSH public key value (i.e. the fingerprint is ignored).

[ORIGINAL REPORT]
Azure is changing the ovf-env.xml file. Instead of passing a fingerprint to the key and obtaining it separately, the SSH public key itself is passed via a new "<Value>" parameters:

        <SSH>
          <PublicKeys>
            <PublicKey>
              <Fingerprint>EB0C0AB4B2D5FC35F2F0658D19F44C8283E2DD62</Fingerprint>
              <Path>$HOME/UserName/.ssh/authorized_keys</Path>
              <Value>ssh-rsa AAAANOTAREALKEY== <email address hidden></Value>
            </PublicKey>
          </PublicKeys>
