Remove usage of maven staging plugin

This plugin will be deprecated soon. We need to remove
the usage of it and migrate to use gerrit-maven-stage jobs
from global-jjb.

After this change is merged, we need to:
- merge https://gerrit.onap.org/r/#/c/77825/
- Verify this new job works as expected
- Remove release-java-daily jobs
