Often, patch and security releases do not require schema migrations or
data migrations. However, if an empty upgrade class and associated
scripts are not defined, the upgrade process will break. With this
change, if a release does not have an upgrade, a noop DbUpgrade is added
to the upgrade path. This approach allows the upgrade to proceed and
for the database to properly reflect the installed version. This change
should make the release process simpler as RMs no longer need to
rememeber to create this boilerplate code when starting a new release.
Beginning with the 4.8.2.0 and 4.9.1.0 releases, the project will
formally adopt a four (4) position release number to properly accomodate
rekeases that contain only CVE fixes. The DatabaseUpgradeChecker and
Version classes made assumptions that they would always parse and
compare three (3) position version numbers. This change adds the
CloudStackVersion value object that supports both three (3) and four (4)
version numbers. It encapsulates version comparsion logic, as well as,
the rules to allow three (3) and four (4) to interoperate.
* Modifies DatabaseUpgradeChecker to handle derive an upgrade path for
a version that was not explicitly specified. It determines the
releases the first release before it with database migrations and uses
that list as the basis for the list for version being calculated. A
noop upgrade is then added to the list which causes no schema changes
or data migrations, but will update the database to the version.
* Adds unit tests for the upgrade path calculation logic in
DatabaseUpgradeChecker
* Removes dummy upgrade logic for the 4.8.2.0 introduced in previous
versions of this patch
* Introduces the CloudStackVersion value object which parses and
compares three (3) and four (4) position version numbers. This class
is intended to replace com.cloud.maint.Version.
* Adds the junit-dataprovider dependency -- allowing test data to be
concisely generated separately from the execution of a test case.
Used extensively in the CloudStackVersionTest.

Cloudstack-8885 added blocked connection listener for rabbitmqeventbus When rabbitmq connections are blocked(for example when rabbitmq is
server is out of space), all the cloudstack threads which does any
action and publishes to rabbitmq(for example login, launch vm etc.) are
all blocked.
Added a blocked connection listener to handle this and unblock the
parent thread.
also updated rabbitmq amqp client to 3.5.4 from 3.4.2
Testing:
I didnt find a way to write tests for this change as of now.
manually tested that login and other cloudstack apis work when the configured rabbitmq server goes out of space and publish actions are blocked.

This commit produces event bus messages to a "cloudstack" topic
in Apache Kafka. Configuration is expected to be found in
/etc/cloudstack/management/kafka.producer.properties and will
generally be of the form:
bootstrap.servers=kafka-host1:9092,kafka-host2:9092
key.serializer=org.apache.kafka.common.serialization.StringSerializer
value.serializer=org.apache.kafka.common.serialization.StringSerializer
There is no way to parameterize the topic yet, and the consuming
code is just place-holder. I think adding a consumer within cloudstack
is very debatable and likely not needed.

Changes;
- Upgrades maven-war plugin to 4.5 (faster war packaging)
- Upgrade spring framework to latest minor release
- Upgrade ehcache, jasypt, httpclient, httpcore and other core dependencies
- Upgrade to latest ipv6 library, fix unit test NetUtilsTest
- httpcore and httpclient are sharing same version variable
- commons-httpclient is different that httpclient, the fix gives it a separate var
- Apidocs failed to generate and get stuck with new reflections version, for now
we will continue using 0.9.8
Newer dependencies can be listed using:
mvn versions:display-dependency-updates -Dnoredist -Dsimulator -P developer,systemvm
Testing;
- Tested using Maven 3.2.1
- Local noredist build with unit tests succeeds
- CloudStack mgmt server started, basic business layer tests work
- Observed 10-15% build time improvement using new maven-war plugin
Branch: bugfix/4.5-8011 (commits are squashed in favour of a linear history)

this checkin adds support for plug-in that provides an in memory event
bus which could be used as alternative to RabbitMQ based event bus. Both
publisher are subscriber should be running with management server to use
in-memroy event bus.
The managed context framework provides a simple way to add logic
to ACS at the various entry points of the system. As threads are
launched and ran listeners can be registered for onEntry or onLeave
of the managed context. This framework will be used specifically
to handle DB transaction checking and setting up the CallContext.
This framework is need to transition away from ACS custom AOP to
Spring AOP.
following changes
- introduced notion of event bus with publish, subscribe, unsubscribe
semantics
- a plug-in can implement the EventBus abstraction to provide event
bug to CloudStack
- A rabbitMQ based plug-in that can interact with AMQP servers to
provide message broker based event-bug
- stream lines, action events, usage events, alerts publishing in to
convineance classed which are also used to publish corresponding
event on to event bus
- introduced notion of state change event. On a state change, in the
state machine corrsponding to the resource, a state change event is
published on the event bug
- associated a state machined with Snapshot and Network objects
- Virtual Machine, Volume, Snaphost, Network object state changes wil
result in a state change event
