[REFACTOR] Migrate to Java 11

[toddbaert]

Based on community feedback and communication with known adopters, we are now able to move to Java 11.

This migration mostly benefits us as maintainers, since it enables new language features and tooling.

Requirements:

• update source and target versions for maven-compiler-plugin
• update to use Java 11 language features
  • there might be some helpful tooling for this
  • recommend not changing any tests during "first pass" to make sure no refactors cause undetected regressions
  • no functional changes should be made simultaneously, only refactors and new API usages
• update any tooling pinned to old versions for Java 8 compatibility

Note:

It's up to individual component owners whether or not they want to consider this a breaking change. The TC will provide a formal recommendation.

@abilashini593, @chrfwow can you update on the plan for it ?
it is blocking #1299 and possibly other work.

@abilashini593 when do you plan to start?

#1303 fixes the majority of CI-related configuration, but we should discuss whether this is already enough to close this issue.

The module-info.java file is something, I think each provider should handle on their own. but do we want to also tackle code improvements, I think we should tackle them separately and this is also in the hands of the provider owners.

wdyt?
