Migrate CIMTool to the Eclipse 4.x (e4) plugin platform

[tviegut]

Migration of CIM Tool from the Eclipse 3.x to the Eclipse 4.x platform (e4) is needed. This migration will introduce no new functionality but instead will address the need to re-baseline CIMTool to e4. Once complete, CIMTool should undergo extensive testing to address any regression issues that may be introduced. Future functionality, enhancements, and roadmap planning will occur later.

For this first release the e4 compatibility layer will be utilized and effectively run CIMTool without significant changes. However, for the time being the more immediate benefits of the e4 platform won't be maximized. If we want to move CIMTool to pure e4, that will be require more work. The current view into the future roadmap is to wait to touch existing older code as we hold out the possibility to have 3.x and e4 plugins run together in the app.

Initial benefits will include:

• CIMTool can run using the latest version of Java - i.e. Java 20.
• UI rendering and responsiveness is much faster than CIMTool on the 3.x platform
• Much more significant heap space - 4GB max OOTB
• Rebranding (i.e. new icons and splash screen have been introduced to reflect the new 2.0.0 release line)
