It would be great if the gerrit code review plugin could add more information about gerrit change being built - ideally the same information that gerrit trigger plugin passes or at least subset of this information.

Particularly following environment variables would be helpful:

• GERRIT_CHANGE_NUMBER
• GERRIT_PATCHSET_NUMBER
• GERRIT_PATCHSET_REVISION
• GERRIT_CHANGE_ID

Also information about change status (open, merged) would be helpful.
