agent: Enable IPv6 connectivity for KVM Agent to Management ServerIPv4 is still preferred, so if the hostname of the Management Server
returns a A and AAAA-record the Agent will still connect to the
server over IPv4.
This situation will however allow to use a hostname which only has
a AAAA-record. In that case the Agent will connect to the Management
Server over IPv6.

The S3 implementation is far from finished, this commit focusses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimalisations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.
With CentOS 7 and Ubuntu 16.04 (to be released) using systemd
it is preferred that CloudStack's Agent is also being started using
systemd.
This commit includes a service file for the CloudStack Agent with
a wrapper script which actually executes Java
It no longer uses jsvc for daemonizing and thus this requirement
has also been dropped for CentOS 7 packaging.
The Agent log output to stdout has also been modified to no longer
include the timestamp as this is done by journalctl.
This has been tested on a CentOS 7.1 machine and the Agent starts,
stops and restarts properly.
Implements a VM volume/disk file activity checker that checks if QCOW2 file
has been changed before starting the VM. This is useful as a pessimistic
approach to save VMs that were running on faulty hosts that CloudStack could
try to launch on other hosts while the host was not cleanly fenced. This is
optional and available only if you enable the settings in agent.properties
file, on per-host basis.

This allows non-root users to add KVM hosts, the user should be an admin or
added to sudoers to execute sudo cloudstack-setup-agent.

This improvements checks for "guest.cpu.features" property which is a space
separated list of cpu features that is specific for a host. When added, it
will add <feature policy='require' name='{{feature-you-listed}}'/> in the
<cpu> section of the generated vm spec xml.

In init.d scripts, the LSB header may specify what kind of service is
provided by an init script. If spaces are used, this means the init
script is providing several boot facilities. We fix that by using an
hyphen.

This allows us to have the Agent connect to the Management Server
over IPv6 if that is listening on :::8250
With this patch it is possible to deploy a IPv6-only KVM Agent where
IPv4 traffic is still forwarded over the bridges, but the KVM Agent
itself does not have IPv4 connectivity.
