Remove usage of maven staging plugin

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/77827/
- Verify this new job works as expected
- Remove release-java-daily jobs
