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.

1. A new implicit planner which extends the functionality provided by FirstFitPlanner.
2. Implicit planner can be used in either strict or preferred mode. In strict mode it tries to deploy a vm of a given account on a host on which vms of the account are already running. If no such host is found it'll search for an empty host to service the request. Otherwise the deploy vm request fails.
3. In preferred mode, if a host which is running vms of the account or an empty host isn't found, the planner then tries to deploy on any other host provided it isn't running implicitly dedicated strict vms of any other account.
4. Updated the createServiceOffering api to configure the details for the planner that the service offering is using.
5. Made db changes to store the service offering details for the planner.
6. Unit tests for testing the implicit planner functionality.
7. Marvin test for validating the functionality.
