feat: update prometheus to 1.5.0

[ash-thakur-rh]

Summary

• Bump Prometheus JMX Exporter from 0.20.0 to 1.5.0 across all Java images (java, java-17, java-11)
• Add new module org.eclipse.jkube.prometheus/1.5.0 and legacy module jboss.container.prometheus/jkube-1.5.0
• Pin prometheus version in org.eclipse.jkube.s2i/bash/module.yaml to avoid ambiguity with multiple versions available
• Add Prometheus sanity tests to all test scripts (executable check, config file presence, javaagent output, AB_PROMETHEUS_OFF disable, JBOSS_CONTAINER_PROMETHEUS_MODULE env var)

Details

Prometheus JMX Exporter 1.5.0 (https://github.com/prometheus/jmx_exporter/releases/tag/1.5.0):

• Supports Java 8+, compatible with all three images (Java 11, 17, 21)
• Adds support for environment variable injection for HTTP Basic auth and JMX authentication

Modules added:

• modules/org.eclipse.jkube.prometheus/1.5.0/ : used by jkube-java (via org.eclipse.jkube.s2i.bash)
• modules/jboss.container.prometheus/jkube-1.5.0/ : used by jkube-java-11 and jkube-java-17

Tests added (all 3 test scripts):

• Verify prometheus-opts script is executable
• Verify jmx-exporter-config.yaml config file exists
• Verify prometheus-opts produces correct -javaagent output with default port 9779
• Verify AB_PROMETHEUS_OFF=true disables prometheus agent
• Verify JBOSS_CONTAINER_PROMETHEUS_MODULE env var is set

Test plan

• Build all three images (jkube-java, jkube-java-17, jkube-java-11)
• Run scripts/test-jkube-java.sh, scripts/test-jkube-java-17.sh, scripts/test-jkube-java-11.sh
• Verify Prometheus JMX Exporter agent loads correctly at runtime
