This feature allows using templates and ISOs avoiding secondary storage as intermediate cache on KVM. The virtual machine deployment process is enhanced to supported bypassed registered templates and ISOs, delegating the work of downloading them to primary storage to the KVM agent instead of the SSVM agent.
Template and ISO registration:
- When hypervisor is KVM, a checkbox is displayed with 'Direct Download' label.
- API methods registerTemplate and registerISO are both extended with this new parameter directdownload.
- On template or ISO registration, no download job is sent to SSVM agent, CloudStack would only persist an entry on template_store_ref indicating that template or ISO has been marked as 'Direct Download' (bypassing Secondary Storage). These entries are persisted as:
template_id = Template or ISO id on vm_template table
store_id NULL
download_state = BYPASSED
state = Ready
(Note: these entries allow users to deploy virtual machine from registered templates or ISOs)
- An URL validation command is sent to a random KVM host to check if template/ISO location can be reached. Metalink are also supported by this feature. In case of a metalink, it is fetched and URL check is performed on each of its URLs.
- Checksum should be provided as indicated on #2246: {ALGORITHM}CHKSUMHASH
- After template or ISO is registered, it would be displayed in the UI
Virtual machine deployment:
When a 'Direct Download' template is selected for deployment, CloudStack would delegate template downloading to destination storage pool via destination host by a new pluggable download manager.
Download manager would handle template downloading depending on URL protocol. In case of HTTP, request headers can be set by the user via vm_template_details. Those details should be persisted as:
Key: HTTP_HEADER
Value: HEADERNAME:HEADERVALUE
In case of HTTPS, a new API method is added uploadTemplateDirectDownloadCertificate to allow user importing a client certificate into all KVM hosts' keystore before deployment.
After template or ISO is downloaded to primary storage, usual entry would be persisted on template_spool_ref indicating the mapping between template/ISO and storage pool.
This implements a CloudStack Prometheus exporter as a plugin, that serves
metrics on a HTTP port.
New global settings:
1. prometheus.exporter.enable - (default: false), Enable the prometheus
exporter plugin, management server restart needed.
2. prometheus.exporter.port - (default: 9595), The prometheus exporter
server port.
3. prometheus.exporter.allowed.ips - (default: 127.0.0.1), List of comma
separated prometheus server ips (with no spaces) that should be allowed to
access the URLs.
The following list of metrics are provided per pop (zone) with the exporter:
• Per host:
o CPU cores: used, total
o CPU usage: used, total (in MHz)
o Memory usage: used, total (in MiBs)
o Total VMs running on the host
• CPU cores: allocated (per zone)
• CPU usage: allocated (per zone, in MHz)
• Memory usage: allocated (per zone, in MiBs)
• Hosts: online, offline, total
• VMs: in all states -- starting, running, stopping, stopped, destroyed,
expunging, migrating, error, unknown
• Volumes: ready, destroyed, total
• Primary Storage Pool: (Disk size) used, allocated, unallocated, total (in GiBs)
• Secondary Storage Pool: (Disk size) used, allocated, unallocated, total (in GiBs)
• Private IPs: allocated, total
• Public IPs: allocated, total
• Shared Network IPs: allocated, total
• VLANs: allocated, total
Additional metrics for the environment:
• Summed domain (level=1) limit for CPU cores
• Summed domain (level=1) limit for memory/ram

store ref table so builtin template is never downloaded completely
In handleSysTemplateDownload method creating template only if there exists no entry
handleTemplateSync will take care of other scenario
- 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 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.
inconsistent state (NotUploaded or UploadInProgress) and doesn't transition to any terminal
state (Uploaded, Uploaded). As a result these volumes/templates cannot be removed. Fix is to handle such
volume/template entries correctly.
The copy command reply can have null size returned, so check and set values

1. Adding the missing Template/Volume URLs expiration functionality
2. Improvement - While deleting the volume during expiration use rm -rf as vmware now contains directoy
3. Improvement - Use standard Answer so that the error gets logged in case deletion of expiration link didnt work fine.
4. Improvement - In case of domain change, expire the old urls
template is downloading, template_store_ref has leftover not in ready
state, when create vm from that template, the code doesn't check either
zone id, nor template_store_ref state.
Conflicts:
engine/orchestration/src/org/apache/cloudstack/engine/orchestration/VolumeOrchestrator.java
2) Corrected some logging in MidoNetPublicNetworkGuru - removed .toString method call on the objects in the log body as toString is called on the object by default when use log4j
Moving default transport for console proxy, SSVM to http.

jlk ported Amogh's patch for 4.3 to master - code base is different
enough that patch has multiple issues.
