feat: sort the YAML output by name and version

[olivierdagenais]

Summary

In order to be able to quickly compare the list of plugins across our Jenkins instances, I added sorting to the YamlPluginOutputConverter.

Please let me know if you would like me to also add sorting capabilities elsewhere.

Manual testing

Given

My local development Jenkins instance, I installed some plugins to test with.

When

I ran the last released version (2.12.11):

java -jar path/to/jenkins-plugin-manager-2.12.11.jar --war "${JENKINS_HOME}/jenkins.war" --plugin-download-directory "${JENKINS_HOME}/plugins" --list --output yaml > plugins-2.12.11.yaml

Then

I obtained the baseline output in a plugins-2.12.11.yaml file.

When

I ran the version with these changes:

java -jar path/to/jenkins-plugin-manager-2.12.12-SNAPSHOT.jar --war "${JENKINS_HOME}/jenkins.war" --plugin-download-directory "${JENKINS_HOME}/plugins" --list --output yaml > plugins-2.12.12-SNAPSHOT.yaml

Then

I obtained the new and improved output in a plugins-2.12.12-SNAPSHOT.yaml file.

Comparing the baseline to it with a graphical diff tool (Meld), we see the old-and-busted version on the left and the new hotness on the right, where we clearly have an alphabetically-sorted list on the right:

Mission accomplished!
