Upgrade to java 1.8.0_292 (#398)
The version of java in openjdk:jre-8-alpine has multiple
vulnerabilities. Because it's been over a year since that image has been
updated, this switches to the openjdk:jre-8 image. This image is updated
much more frequently.
Succesfully built from my box using:
```
sudo docker build -f docker/Dockerfile -t apachepulsar/pulsar-manager:v0.3.0 .
```
I also confirmed the image still works by setting an admin password and
logging into the dashboard. I used the existing docker-compose.yml for
this test, but changed the tag to v0.3.0.
