check_es_system

This is a bugfix release and affects a fix for the readonly check type. Before 1.12.1, the readonly check would silently return OK even if the check doesn't work due to missing privileges on the Elasticsearch cluster.

This release contains multiple enhancements:

• Additional authentication method using SSL settings (with key and certificate)
• Additional CPU usage check
• Additional "local" node parameter. Certain checks (cpu, mem, disk, jthreads) can be executed with the additional -L flag.

The base work was submitted in PR #41 . To assure backward compatibility and other improvements, the PR #44 replaced PR 41 and was finally merged.

This version 1.11.1 fixes two bugs.

• Invalid authentication is not properly handled and did not result in correct plugin behaviour (output and exit code) on the check types readonly, master and tps

• Invalid domains submitted by -H parameter were not properly handled and resulted in the plugin to simply return OK (exit code 0) when a HTTP status 200 came back as a response.
