Groovy - Generates high number of class loads

[brunovg]

The last implementation of groovy script (StrictSecurityMode ON) is generating a high number of class loads.

We decided to use groovy component directly from Apache Camel, with a pre validation on flow install.
If validation fails on install, the flow installation is aborted.

We need to test this further, but also extend the valdation to block "evaluate" calls in strict mode.
