[#69995468] Add another disk to Vagrant

Adding another disk for log backups to use.
[#69995468] Add a user for log backups.

Add a second user to receive transition log backups.
[#69995468] Add and mount a LVM volume for log backups.
[#69995468] Allow sftp for rssh users.

Duplicity seems to use `sftp` instead of `scp` even if you tell it to use
`scp` as a protocol

I would have preferred to use `sshd`'s internal `sftp` subsystem but the
puppet module we are using doesn't easily allow that change.

[#70929368] Set resolv.conf to Carrenza's NSs

The `resolvconf` package is currently installed on the machine in Carrenza
but no nameservers are specified so it can't resolve anything.

Fix this by managing resolvconf with a module that we've used elsewhere and
point it at Carrenza's recursive nameservers (obtained by support ticket).

This won't have any effect within Vagrant because it doesn't set nameservers
if it detects that DHCP is being used:

Refactor jenkins.sh for Carrenza

To make it clearer that it does both "box" and "net". I've also moved
`fog_credentials` and refactored some of the Carrenza specific information
out of it so that we can re-use it.
Remove vcloud-net-spinner config and script

This wasn't used; we're using vcloud-edge_gateway instead.
Simplify vcloud README

We shouldn't need to know about the guys now that we definitely have a
Jenkins job which handles both "net" and "box".
