Skyline - collected data

Before sending collected data to VAC, Skyline Collector (ccf-collector) store cache files to local.
These cache files (formatted by JSON) are located under "/usr/local/skyline/ccf/output" directory. These cache files are compressed in gzip format.
For example, output_<TIMESTAMP>_Topology.json.gz is a full topology data of endpoints.
These files are retained until the number of total files reaches 1000 OR the size of total files reaches 500 MB.
