check_es_system

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.

This fixes #30

• Set jq as new default json parser (was: jshon)
• Plugin now shows the names of the found read_only indexes when using jq as json parser
