Method logging aspects

[dschiese]

Added aspects to log method executions for both, components and pipeline (pipelines as components are handled as components, i.e. their process() method is the anchor.

Handling

• no environment variables have been added, therefore, no adjustments need to be undertaken
• The aspects need to be compiled with the target jar, therefore, the Qanary commons must be available. Currently, the Component Parent includes this, however, not every component relies on the parent. Here, the commons have to be included manually or by setting the parent to Component parent. (Actually, is there a reason for this?)

Needs to be done:

• Switch to turn off logging (See different issue, too!)
• Pipeline Pointcuts
• Tests as far as possible
