Adding Apache CXF to assembly
Updated etc/jre.properties to make CXF work

In this commit I've also changed the Karaf integration test
to make use of the custom distribution we are building. This
makes the test a lot more relevant and useful.
Upgraded to Karaf 2.2.10. Fixes #134
Merge pull request #135 from andreisavu/api-step-1

First step towards adding a REST API. Part of #119
Add the ability to register templates as xml files

No need to recompile the code or install new bundles. You
can even edit / add new templates while the application
server is running or during bundle / feature installation.

Changes:

* replaced Java pool templates with xml file (still part of core)
* implemented file system watcher based on Felix fileinstall for pool templates
* downgraded osgi framework from 4.3.2 (1.6) to 4.2.0 (1.5)
* removed Activiti process engine test code (used just for learning)
* disabled kar deployer
* improved listing for provisionr:templates
* the final distribution no longer installs by default

Merge pull request #127 from andreisavu/issue-127

Refactor templates (remove the need for Java code)
added spot instances stubs
creating a spot instance request
checking if spot instances are open or not
Initial draft for spot instance requests from the Amazon tutorial.
Moved the logic for spot requests in separate activities. Working process test for this case.
Fixed review issues

- added generic option for provider-specific properties with tests
- fixed formatting and comments
- better collection handling with Guava
- used polling & stopwatches instead of just sleeping when waiting for spot requests

refactored test with mocks to prevent it from failing in CI
