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.

Revert "CLOUDSTACK-1744: It's due to db upgrade issue. On master,
deploydb will upgrade db to 4.2, which will update vm_template's
image_data_store_id, while deploydb-simulator adds a new column in
vm_template table, which doesn't set image_data_store_id, thus causing
NPE."

Introducing the simulator spring context -
simulatorComponentContext.xml.in. This separates the simulator beans so
that production deployments don't have the simulator in them. Context is
enabled with -Dsimulator as part of the developer profile.
Also adding config files - Simulator Config for advanced zone and basic
zone deployments under setup/dev.

well), and populate UUID column in seed data sql script.

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.
