Host-HA offers investigation, fencing and recovery mechanisms for host that for
any reason are malfunctioning. It uses Activity and Health checks to determine
current host state based on which it may degrade a host or try to recover it. On
failing to recover it, it may try to fence the host.
The core feature is implemented in a hypervisor agnostic way, with two separate
implementations of the driver/provider for Simulator and KVM hypervisors. The
framework also allows for implementation of other hypervisor specific provider
implementation in future.
The Host-HA provider implementation for KVM hypervisor uses the out-of-band
management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
a host.
The Host-HA provider implementation for Simulator provides a means of testing
and validating the core framework implementation.

- Bump spring-framework version to 4.x and Jetty to version that runs with JDK8
- Bump servet dependency version
- Migrate spring xmls to version 4, fixes schema locations that are 3.0
dependent in various xmls.
- Fix failing tests due to spring upgrade
(Thanks @marcaurele Marc-Aurèle Brothier for fixing them)

The simulator uses the default planners of cloudstack and does not
require a separate planner context (as of now). This was just c&p from
baremetal planners.

ACS is now comprised of a hierarchy of spring application contexts.
Each plugin can contribute configuration files to add to an existing
module or create it's own module.
Additionally, for the mgmt server, ACS custom AOP is no longer used
and instead we use Spring AOP to manage interceptors.
And the components-simulator.xml configuration. Both are unused as we
use Spring injection now.
Remove unused rebootVM method

Multiple fixes:
1. changes to the mvn configuration
a. include simulator to client.war
b. activate simulator by profile
2. templates for simulator
3. developer prefill for simulator
a. Use deplydb-simulator to setup simulator db
4. Inherit components-simulator.xml from components.xml
5. ListVolumesCommand missed for MockStorageManager
6. Include simulator properties into utils/db.properties
TODO:
Secondary storage VMs don't come up because ComponentLocator doesn't
retain a unique set of adapaters by name. Fix this in subsequent
checkin.
