Switch to use JDK11 for CI and Docker images (apache#10580)

### Motivation

There has been discussions on the Pulsar dev mailing list and in Pulsar Community meetings about making the switch to use JDK11 for CI and for the Pulsar docker images in 2.8.0 release.
The code is kept binary compatible with Java 8 and is compiled in JDK 11 with the `--release 8` javac option.

### Modifications

- Use Java 11 to run all GitHub Actions builds
- Switch base images of docker images from OpenJDK 8 to OpenJDK 11.
- Fix dependencies and license files when using JDK 11.
