    Fix PrometheusMetricsTest on source tarball (#8702)
    
    When you run the tests from the sources in the source release tarball there 
is no git reference and we are publishing on the metrics a placeholder.
    
    
`pulsar_version_info{cluster="test",version="2.7.0",commit="${git.commit.id}"} `
    
    I noticed the problem because PrometheusMetricsTest.java is failing on 
2.7.0 sources
    
    The fix is to detect this fact an publish only an empty string.
    The change affects PulsarVersion, that in turn is used in Prometheus 
metrics endpoint
