This implements an out-of-band management plugin for nested-cloudstack
environments where the hypervisor host is a VM in a parent CloudStack environment
that is used as a host in the (testing) CloudStack environment. This plugin
allows power operations to translate into start/stop/reboot of the VM (host).
The out-of-band management configuration accepted are:
- Address: The API URL of the parent CloudStack enviroment
- Port: The uuid of the (host) VM in the parent CloudStack environment
- Username: The apikey of the user account who has ownership on the (host) VM
- Password: The secretkey of the user account who has ownership on the (host) VM
Note: change password of the oobm interface is not support by this plugin

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.

Increases/sets ulimit for cloudstack agent and management. This would fix
any issues with opening more files than permissible limit (usually 1024-4096).

Use available context to filter a metrics view based on zone, cluster, host
in the context object. This fixes metrics view filtering when metrics view is
viewed via Zone->Compute and Storage-> for a resource.

KVM hosts on shared storage failure was accepted by mgmt server with the
host state as Up, even though there was no primary/shared storage available on
it. This patch offers a quick fix by throwing an exception in the storage monitor
which connects storage pool on host. The failure is trapped by agent manager
that disconnects the agent without any investigation.
Based on Lab tests, KVM agent may take upto 2 minutes to attempt NFS mount when
the storage is inaccessible (firewalled, or shutdown) before returning back with
an error. It is safe to assume that this won't add pressure on mgmt server due to
several reconnection attempts, and KVM agent would retry reconnection every 2
minutes.
For such KVM hosts, where failure happens due to storage issues; they will be
briefly put in Alert state but will be mostly be in Connecting state during which
the KVM host attempts to mount/reconfigure NFS storage pool.

Removes order by id which is not necessary as we already do order by
sort_order. An additional order by seems to have caused mysql errors
in some environment, though it was not reproducible with MySQL 5.5/5.6/5.7
but this can be safely removed as it's not necessary.

In case of rpms, the commands.properties file is bundled at
/usr/share/cloudstack-management/webapps/client/WEB-INF/classes/commands.properties
In case of a rpm upgrade, new rpms won't ship with commands.properties file. For
existing installations this copies the commands.properties file to
/etc/cloudstack/management

Support access to a host’s out-of-band management interface (e.g. IPMI, iLO,
DRAC, etc.) to manage host power operations (on/off etc.) and querying current
power state in CloudStack.
Given the wide range of out-of-band management interfaces such as iLO and iDRA,
the service implementation allows for development of separate drivers as plugins.
This feature comes with a ipmitool based driver that uses the
ipmitool (http://linux.die.net/man/1/ipmitool) to communicate with any
out-of-band management interface that support IPMI 2.0.
This feature allows following common use-cases:
- Restarting stalled/failed hosts
- Powering off under-utilised hosts
- Powering on hosts for provisioning or to increase capacity
- Allowing system administrators to see the current power state of the host
For testing this feature `ipmisim` can be used:

- Reduces SSL handshake timeout to 15s, previously this was only 10s in
commit debfcdef78
- Adds an aggresive explicit wakeup to save the Nio main IO loop/handler from
getting blocked
- Fix NioTest to fail/succeed in about 60s, previously this was 300s
- Due to aggresive wakeup usage, NioTest should complete in less than 5s on most
systems. On virtualized environment this may slightly increase due to thread,
CPU burst/scheduling delays.
