XD-2094 XD Cluster view

- Add `containers` tab
  - this renders the contents of `cluster/containers` REST endpoint
  - update the containers info with
     - groups
     - deployed modules
       - if the management port/jolokia are enabled, then deployed modules will also display message rates which can be configured via property in `routes.js` `$rootScope.enableMessageRates`
     - `shutdown` option if the management port is enabled
- Add tooltip on container and deployed modules values to display container and deployment properties respectively.
- Add confirm dialog for container shutdown
  - Disable shutdown action if management port is disabled
  - Align container id as plain text in the table
XD-2094 Add `xdPopover` Directive
Use strict REST domain objects

 - For `ModuleMetadataResource`'s module type and deployment status,
use `RESTModuleType` and `RESTDeploymentState` that represent the
module type and DeploymentUnitStatus.State.
XD-2095 WebUI: Support stream deployment props

- Add support to specify deployment properties when deploying stream
- Add a form that accepts text box for `deployment properties` and submit `deploy` action
XD-2169 - Create standalone list of deps for project

Switch from platform-managed dependency versions to a local file
compatible with the `versionManagement` mechanism of the Spring Boot
Gradle Plugin (initially, the file is a clone of the versions list
found in Spring IO 1.0.1.RELEASE).

This is necessary in order to allow the project's dependency list to
evolve independently from Spring IO (e.g. in order to upgrade Spring Boot).
XD-2146 Upgrade to 1.1.7.BUILD-SNAPSHOT
XD-1811 Custom module registry location

- In addition to `xd.module.home` and `classpath:/modules` as the default
module registry locations, an additional `xd.customModule.home` is provided
to let the user define any specific supported URL path for the module registry.
- Add an entry for `xd.customModule.home` in servers.yml so that user can
specify it.

Fix description not to use http:// location

Handle customModuleHome placeholder

 - Add `isActive()` to ModuleRegistry
 - Include only the active module registries to the DelegatingModuleRegistry
Comment out properties
Assign null default for custom module registry

 - Having `null` as the default value for custom resource module
registry will let us handle the look up methods return null/empty
values.
XD-1519 Adds missing Job Registry schema files allowing to use GemfireXD and Derby-style databases as main Spring XD storage.

Added files is a copy of MySQL schema files. Works fine with GemfireXD 1.3.0.
