Plugin should report when not all issues are returned

The plugin should provide some kind of report when not all requested issues have been returned.

This information is available in the response, for example (from -X output):

Payload: {"expand":"schema,names","startAt":0,"maxResults":100,"total":141,

If total is greater than maxResults, then some issues have been dropped.

This could be reported as a Maven warning and/or added to the report itself.
