Configure and enable core uploader (#1522)

* If core-storage secret key is available, add to /etc/sonic/core_analyzer.rc.json and enable & start core_uploader service
If https_proxy is provided, update /etc/sonic/core_analyzer.rc.json.

* Check the entire dict path before de-referencing.

* Improved regex per comments.

* Fixed syntax error.

* Add a sample file for newly introduced ansible facts.wq

* Removed a redundant empty line.
