Add JIRA_ISSUES_SIZE to the JiraEnvironmentVariableBuilder

[rantoniuk]

Contributed by @mupakoz in #119

Adds JiraIssuesSizeEnvironmentVariableBuilder build step which enables saving number of issues matching a JQL query in a environment variable of specified name.

I came up with this idea for a new feature when I wanted to fail the build in case there are issues on JIRA that were resolved but still untested. Thanks to the plugin we can save the number of issues we are interested in and then use it in the next steps (for example a shell script or a conditional step).

Pull Request Overview

Adds support for a new environment variable (JIRA_ISSUES_SIZE) that captures the count of issues matching a JQL query.

• Builder (JiraEnvironmentVariableBuilder) now computes and logs issue count and passes it to the action
• Contributing action (JiraEnvironmentContributingAction) stores and exposes the new size variable
• Tests and help documentation updated to cover JIRA_ISSUES_SIZE

• The new JIRA_ISSUES_SIZE log message isn’t asserted in testPerformAddsAction. Consider adding a verify(listener.getLogger()).println(...) check for the size update to ensure full coverage of the new behavior.

        boolean result = builder.perform(build, launcher, listener);

src/main/java/hudson/plugins/jira/versionparameter/JiraVersionParameterDefinition.java:40

• [nitpick] If the parent class provides a super(name, description) constructor, consider using it directly instead of calling super(name) followed by setDescription(description) for clearer intent and less boilerplate.

        super(name);

src/test/java/hudson/plugins/jira/JiraEnvironmentContributingActionTest.java:20

• [nitpick] The test methods were made public, whereas other JUnit Jupiter tests in this module remain package-private. Consider reverting to package-private for consistency with the existing style.
