SDN-R goes Sodium and Java11

Infrastructure Jenkins => Check
Migration strategy BingBäng vs. Smooth => Specify
- SDNC should completely move to J11
- CCSDK ... J8 and J11?
ODL Base image with J11

	Solution 1 (versioning)	Solution 2(artifcat-suffix)
	ccsdk-parent (version): neon java 8: 2.0.0 neon java 11: 2.0.0-SNAPSHOT (Test) sodium java 11: 2.0.1 features: neon java 8: 1.0.X sodium java 11: 1.1.X	ccsdk-parent (artifactId): java 8: unchanged java 11: <artifactId>-j11 features: java 8: unchanged java 11: <artifactId>-j11
this has impacts on		docker image names: sdnc-j11-image
pros		Piece by piece migration path
cons	Java code and libs are not compatible Code adaptions for J11 are necessary Compilation also necessary	different artifacts with same function in nexus feature names for container to start will be renamed
open points		neon version code compatible with sodium j8?
